What happend to rays of light when they are refracted by a convex lens?
Now suppose that the rays of light are traveling through the focal point on the way to the lens. These rays of light will refract when they enter the lens and refract when they leave the lens. As the light rays enter into the more dense lens material, they refract towards the normal; and as they exit into the less dense air, they refract away from the normal. These specific rays will exit the lens traveling parallel to the principal axis.
What happens to a ray of light that slows down when it hits a new medium at an angle?
The change in speed causes the light to bend. If it is travelling from an optically dencer to an optically rarer medium the ray will bend away from the normal. But if it is travelling from an optically rarer to an optically denser medium then it will bend towards the normal.
What is the direction of a shadow?
Away from the light.
What type of energy does a light bulb emit?
Mainly heat and light. Heat is carried away through convection, but also radiated away as infrared light, a kind of electromagnetic wave (as is light).
When light moves from glass into air at an angle is the light refracted toward or away from the normal?
it bends
What is use of optical bench?
Optical bench is used for the moving the light in straight away from the photocell.

What is marginal rays?
Marginal rays are the light that passes through an optical system that is away from the optical axis.

Why does a swimming pool look not as deep as it actually is?
The rays of light refract from water to the air so they refract away from the normal and this means that the bottom of the pool seems less deep than it is.
Do lenses reflect or refract light?
Light refracts when it passes across the boundary of two media having different optical densities (refractive indexes). If the light stated in the question had done this, then it is refracted.
Do lenses refract light?
when light falls from air on lens it undergoes refraction as lens is denser than air light on entering lens move towards normal and is bent and while leaving moves away from normal
What is meant by optical augmentation principle?
Optical Augmentation (OA) is the methods behind detecting optical devices, such as rifle scopes, cameras, binoculars, etc. An active light source is used to illuminate optical devices, which in return give off a "cats-eye" effect, giving away their position.
What are the advantages of opto mechanical mouse?
The laser of the optical mouse may bounce off certain colors and shapes on a mouse pad.There are no disadvantages to a optical mouse. The optical mouse just works better and smoother than the ball mouse, and you never have to worry about the ball getting dirty or hanging. I would suggest getting an optical mouse and throwing the ball mouse away.
Is Mercury a light year away from earth?
No it is not. Mercury is closer than a light year away.=======================================Pluto ... and anything closer to the sun than Pluto is ... is never more than about 400 light minutes from Earth.From here to the sun is about 81/3 light minutes.
How long does it take for light to hit a quasar 58656960000000000000000 miles away?
It never gets here. Its light took a billion years.
How is optical density related to refraction?
As you should know, as light travels from one medium into another more optically dense medium (such as from air into water) the light is refracted towards the normal. But why does the light appear to bend and refract? Light acts not only as a particle, but also as a wave. When the light hits the more optically dense medium it slows down. This also happens with water waves. As the waves come towards the shore the ocean becomes more shallow and they speed up, when the water waves speed up they bend away from the normal. The same thing is happening with the light waves. As light waves are hitting the more optically dense material, because they slow down they oppose and opposite effect to the water waves and bend towards the normal. I hope this helped. :)
