What else can I help you with?
What is the bending of light called when it passes from one transparent material to another transparent material?
The word is refraction. It is better to say that light changes direction even though the term "bend" is often used. The phenomena is intrinsic to waves that pass through the boundary between to mediums, e.g. water waves exhibit refraction when moving from an area of deeper water to shallower water. The concept of refraction is clear and simple only when the boundary between the two mediums of the wave is flat. When an interface is not flat, the refraction, reflection and transmission concepts need a more sophisticated characterization. It should be observed that the refraction of waves at an interface is accompanied by a change in velocity of the waves as well. This is most commonly discussed for light where the speed of light in a medium is equal to the speed of light in a vacuum divided by the index of refraction of the medium. (This can be generalized to other types of waves.) Regarding wave speed and wave refraction, one can not say that one causes the other. They must happen together for everything to be consistent.
What does the amount that light refracts depends on?
It depends on the REFRACTIVE INDEX of the Medium it is traveling though. That INDEX is directly dependent on the DENSITY of the Material.
Why does a straw appear to be bent in water?
When light passes from one medium to another (e.g. air to water), it changes speed and direction, causing refraction. This refraction makes the straw appear bent at the surface of the water even though it is actually straight.
How is cinematography is related to refraction of light?
The light, passing though the lens of a projector is diffracted so that a small picture is projected as a large image.
Why do the focal length decrease as the thickness of the lens increase?
The angle of refraction increases, though it's a function of curvature rather than actual thickness.
What is the term for the material though which a waves moves?
Matter
Does material have more than 1 meaning?
yes it has 3 but i don't know them i kow that though Material=fabric Material=physical substance or matter. Material=pertinent. She sewed the material. He handles the radioactive material. That is not material in this case.
What material begins with l?
lead there are probably more though
Can you wipe your laptop screen with baby wipes?
Probably, though they'd better be designed for cleaning lenses and/or monitors.
What is the second strongest building material?
The second strongest building material is obsidian even though it can't get blown up.
What is a very fine grained material used in the manufacture of bricks?
Clay. Mud (with or without clay) is the oldest material from which bricks are made. Modern masonry bricks are commonly made with clay, though they can be made with calcium silicate, shale or other materials. Need more information on this venerable construction material? Got a link for you to the Wikipedia article on the brick.
Why use concrete?
It is a low cost material with excellent properties though it is weak in tension. There is also a lot of experience using the material.
