In what medium the speed of light will be minimum?
The speed of light is a set speed at which all electromagnetic waves travel at in a vacuum. It is 3*10^8 meters/second... That being said, when light, or any other EM wave, travels through a medium it will slow down. Every material has an index of refraction which is the ratio of the speed at which light travels in a vacuum, to the the speed it travels in that material. If you know the index of refraction, you can use Snell's law to determine the speed light will travel through a specific medium. Every medium is different, however a rule of thumb is the denser the medium, the slower light will travel through it. For example, light travels faster in the atmoshpere than it does in water.
How is the index of refraction of a substance related to the speed of light in the substance?
The substance's index of refraction isSpeed of light in vacuum / Speed of light in the substance
Does light slow down when it travels through matter?
Light slows down when it travels through matter.The only time light travels at is maximum speed, c, is in a vacuum.
What happens to speed of light when travel through plastic?
When light travels through anything that is not a vacuum, it will usually slow down.
Light travels faster in?
light travels faster in vacuum.
does light travels three-fourths as fast through water as it does a vacuum. what is water's index in refraction?
Water's index of refraction is 1.333
How would you describe the behavior of light as it travels from the container to the air or as it travels in different media?
Light always takes the shortest path possible through any medium. As such, when it travels through a vacuum, it travels in a straight line (no refraction). When it travels through the air, the molecules in the air scatter it very slightly, causing some diffusion and refraction, depending on the composition of the air through which it passes. When it travels through water, the shortest path through that medium is not a straight, collinear line from the point of incidence...it is actually offset by a small angle (the angle of refraction). The bent path that light takes through water or another substance is actually the shortest path available to it through that medium.
When solar energy travels from the sun through a vacuum of space to the earth?
Energy from the sun travels through the vacuum of space by radiation.
What is the index of refraction for a material in which light travels with a speed that is 80 percent the speed of light in a vacuum?
It's 1/0.8 = 1.25
Does light travels through vacuum by radiation?
yes

The average speed of light is greatest in?
The velocity of light travelling through a material relates to the index of refraction of that material. In this group, air has the lowest index of refraction, follow by water, fused quartz, and crown glass. This means like travels the fastest through air, then water, then fused quarts, and finally glass.
What happens when light passes through vacuum?
it travels at c (speed of light in a vacuum)
Why can radiation travel in a vacuum?
yes as radiation travels from the sun through a vacuum to earth
What does light travel faster through?
Light travels fastest through vacuum.
How can you know that light travels through a vacuum?
light travels from sun to earth through vaccum, so its easily understood
Does light travels slowest through space?
As the medium through which light propagates in space is closes to a vacuum, light propagates very well in space. However, it travels at the same speed as it would on earth, as light travels at 299,792,458m/s in a vacuum, regardless of where that vacuum is located. the light travels in same speed whether it travels in space or earth.
