Optics is the study of how light (moreso Electromagnetic Radiation) travel and interact with objects (solid state physics, electrodynamics etc.). Optical illusions deal with how light is interpreted by the human brain. So optics studies how light gets to the eye, optical illusion is about how the brain perceives that light.

What is the main cause of an optical illusion?
I believe we have optical illusions to make our eyes and brains think in different ways then they normally think! Without optical illusions, we wouldn't look at things the way we look at them... i guess(?).
Are illusion harmfull?
Some optical illusions- akin to vandalized to tampered-with traffic signs, could cause vehicular accidents which might take human life.l It would be extremely difficult to prove this as a cause- unless it was a traffic sign that had been painted over no through traffic to ( Through Traffic) or something of the kind. in dim light , even a skilled motorist might be taken in, it can happen.
Why are your brains tricked by optical illusions?
cause its hard to see the different pics. in the picture
What is it called when atmospheric conditions cause nonexistent bodies of water to be seen?
An optical illusion that is caused by atmospheric conditions in which nonexistent bodies of water are seen is commonly referred to as a mirage. This is most common in extremely hot climates, and although the most common mirage is of bodies of water, there are other illusions that may appear to a person, as well.
What is the relationship between optical illusions and physics I want to know how physics is involved when looking at an optical illusion.?
There are multiple types of optical illusions. There are those that are real and the effect actually exists because of various physical phenominon, mostly assosiated with optics, and there are the type that cause our senses to be fooled. I will address the latter. What creates an optical illusion is different depending on the set up. Some are created by the eye itself and others are created by the brain's interpretation of the eye's messages. Some examples. A negative after-image. This is what you see when you stare at a certain picture for a very long time. The rods and cones in your retena become tired after the same messages are repeatedly fired. The "after immage occurs when you then look at something else. The cones and rods of the retena continue to fire but the tired reciever's signal is not as powerful. This means that you do not pick up certain colors. This lack of some colors causes the negative after image. Another illusion is the common "spinning wheel" illusion. Where a circle is created by sucessive radial lines. The eye is always moving in very small ammounts, even when you try to keep it still. When you move the eye tries to keep track of the lines using many small jumps. These jumps trigger the brain to experience the strobeoscopic effect which causes it to believe there is motion when there is not. Yet another type of popular illusion is created by creating a false perspective. These are commonly known as "Magic Eye" illusions. When the picture is held out of focus at the correct depth, the two different pictures that each eye sees overlap. This is the same thing that our eyes do to see immages in 3-D. The brain takes the two perspectives and adds them together. In this case it is fooled. The pictures overlap and the brain adds them together to create a 3-D immage. These are just a few explanations why optical illusions work as they do. Each and every type of illusion utilyses a different effect created by they eyes and brain.
Why does rod bent when immersed in water?
It doesn't. It only appears to because of an optical illusion. Refraction due to the water alters the apparent position of the rod beneath the water. This is the same cause for the apparent reduction of depth in a swimming pool

How does the refraction of light as it passes from air into water cause optical illusion?
I'm only twelve in sixth grade believe it has something to do with reflecting and bouncing off of certain thing's. Sorry I don't have any more info.
Entertaining your Mind with Optical Illusions?
Optical illusions are pictures that use color, patterns, and light to trick the eyes and brain. When viewing an optical illusion, what the eyes see is interpreted by the brain, but the brain's interpretation does not match the true image. In fact, the brain sees something that is not really there. Optical illusions are fun to look at, but they also help scientists to learn how the brain works. Many optical illusions were created just to study how the brain processes visual information. There are three basic types of optical illusions: literal, physiological, and cognitive. Literal optical illusions form images that are unlike the objects that create them. The best way to understand a literal illusion is to look at one. An example of a literal illusion is the painting Bakery by Octavio Ocampo. In this painting, a woman sits in front of shelves full of bread in a bakery. However, the way the bread is arranged appears to form skulls. Another famous example of a literal optical illusion is the painting All Is Vanityby Charles Allan Gilbert in which a woman sitting at a vanity table looks like a skull when viewed from further away. Physiological illusions happen when excessive stimuli such as brightness, color, movement, or tilt, for example, cause the eyes or brain to see something that is not there. These illusions can also occur when stimuli compete. The Hermann grid illusion is a famous example of a physiological optical illusion. The Hermann grid is a white grid on a black background. When looking at it there appear to be gray dots at the intersections of the white lines, although in reality there are no gray dots. This is due to a physiological phenomenon called lateral inhibition which is when light and dark photoreceptors compete with each other and one part wants to become active and the other does not. This causes a perceptual illusion of gray dots on the grid. Cognitive illusions occur when the eye and brain make unintentional inferences. There are four types of cognitive illusions: ambiguous, distorting, paradox, and fictional. Ambiguous illusions offer two interpretations of a picture or object, but both can't be seen at the same time. A famous example of an ambiguous illusion is the Rubin vase, which either looks like a white vase or two face silhouettes facing each other. Distortions in length, size, and curves appear to be present in distorting illusions. A famous example of this type of illusion is the arrow illusion, otherwise known as the Mueller-Lyer illusion. In this illusion there are two lines that are the same size but one has the ends pointing in and one has ends pointing out; most people say that the line with the ends pointing in is longer. Paradox illusions are objects that are impossible in real life but look real in drawings, such as the Penrose stairs, which seem to go on forever without getting any higher. This illusion is due to the faulty belief that adjacent edges have to meet. The Penrose triangle is another example of a paradox illusion. Fictional illusions are only seen by a single person; they are actually hallucinations. They can be induced by alcohol or drugs, or by health conditions such as schizophrenia. Examples of fictional illusions are seeing double of one object or seeing something move when it really doesn't. Literal, physiological, and cognitive illusions all deceive the eyes and brain. People have been fascinated by optical illusions throughout history, and continue to be fascinated by them today. Paintings, books, and drawings of optical illusions have become famous because they are fun to look at; however, they also help scientists to discover how the brain works. Fun and science often go hand in hand.

Does doubling the angle of incidence cause the angle of refraction to double?
No, doubling the angle of incidence itself will not cause a doubling of the angle of refraction.
What is changed to cause refraction?
Refraction is a change in direction of a wave due to a change in its transmission medium.
How do prisms create a spectrum of colors?
Prisms create spectrum of colors by the cause of refraction.
Which property of light cause Shadow?
refraction
What causes a pencil to look bent in water?
Water can cause a distortion of the light and in turn causes optical illusions. The water refracts light in such a way that objects viewed through light can appear bent, or angled sharply. This is a function of refraction.
Why does person's legs appear shorter under the swimming pool?
Due to refraction. :p It makes you perceive that the persons legs are shorter. To think this is all to do with the simple distortion of mediums :)Sources: My year 8 science class.
What phenomenon cause color of visible light to be separate by a prism?
Refraction is the phenomenon causes colors of visible light to be separated by a prism.
What cause refraction of light to happen?
This is caused by a change in the speed of light .
