Why does a flashlight shine brighter on objects to which it is closer?
A flashlight appears brighter on closer objects due to the Inverse Square Law of Light, which states that light intensity decreases with the square of the distance from the source. This means that the closer an object is to the flashlight, the more light it receives per unit area, making it appear brighter.
What is the name for dark objects that show more light than pale ones?
Luminous objects emit their own light, while illuminated objects reflect light they receive. This can sometimes make dark objects appear brighter than pale ones under certain lighting conditions.
Which is the brighter - the light coming in or the light from the flashlight?
Sun light is more brighter than the light from flashlight in house.
Which is brighter the light coming from in or the light from the flashlight?
Sun light is more brighter than the light from flashlight in house.
Does blonde hair absorb the light?
Blonde hair reflects more light compared to darker hair colors, which can make it appear brighter. However, it still absorbs some light, as all colored objects do to some extent.
What is the definition of reactive to light and accommodation?
Reactive to light refers to pupils constricting when exposed to light and dilating in the dark. Reactive to accommodation means pupils constricting when focusing on near objects and dilating when looking at far objects.
Is there more photons in brighter light?
Yes, brighter light typically means more photons are present because brighter light has a higher intensity, which is measured by the number of photons hitting a given area over time. So, in a brighter light source, there are indeed more photons emitted.
How people can see objects?
People see objects - because light is reflected back to the person viewing.
Why should the lens of a normal eye be fatter to lookat near objects and thinner to look at distance object?
The lens of a normal eye changes shape to focus on objects at varying distances. When looking at near objects, the lens needs to be thicker to refract light properly onto the retina. Conversely, for distant objects, a thinner lens is needed to allow the light to converge properly on the retina for clear vision.
What would green look like under a green light?
Green objects under a green light would appear brighter and more vibrant as the green light would enhance the color by adding more green wavelengths to what is already there. The objects would likely blend in with the background if the light is the same shade of green.
What color object would reflect more light?
A white object would reflect more light compared to a black object. White objects reflect most of the wavelengths of visible light, making them appear brighter, while black objects absorb most of the light, appearing darker.
Is a 24volt light brighter than a 12volt light?
yes
