If the speed of light was the same in all materials would a lens cause light rays to bend?
No. Without refraction at a boundary between media with different refractive indices, lenses wouldn't work. The only way we would have of forming real images would be with curved mirrors.
Why is clear glass is an example of an transparent material?
Whenever light, while traveling through a medium such as air, encounters a substance with a different index of refraction, some light will pass and some will reflect off the surface. The angle, and the difference in the two indexes will determine the reflective properties of the glass. Specifically, light is composed of alternating electromagnetic waves. When you solve Maxwell's equations for these waves encountering a surface, reflection is discovered.
What is the angle of refraction when the angle of incidence is equal to the critical angle?
Quick Answer:The angle of incidence is not equal to the angle of refraction.The angle of incidence is equal to the angle of reflection.Better Answer:(This answer applies to all waves, e.g. sound, ripples, earthquakes, but the answer is given in terms of light waves.)The angle of incidence never equals the angle of refraction except in the peculiar circumstance when there is an interface between two materials of exactly the same index of refraction.The angle of refraction is the direction of the wave exiting the surface and the angle of incidence is the angle entering the surface.These two angles are related by Snell's law and by Snell's law one would conclude that the index of the medium of the incident beam would be exactly the same as the index of the transmitted beam. In optical terms, it would mean the wave propagates as though there were no interface and the two mediums were actually the same medium. In that case, there would be no reflection as well.So, one does not expect this to happen, not because it can't, but because the wave travels through the surface as though the surface did not exist and that is both unusual and uninteresting.
What happens to light waves when two materials do not have similar indexes of refraction?
Nothing happens to light waves at all. UNLESS the two materials happen to be right next to each other AND the light tries to cross FROM one INTO the other one. Then things get very interesting.
What are the 2 conditions when the direction does not change on refraction?
-- Light approaches the boundary between any two media along the normal direction. -- Light approaches the boundary at any angle and the indexes of refraction of both media are equal.
Does total internal reflection follow the laws of reflection?
Yes, 100% reflection occurs to light approaching the intra-media boundary at some angles. When light passes from a more dense medium to one that is less dense it bends away from the normal (the imaginary line perpendicular to the boundary where the transfer happens). So there is an angle of incidence corresponding to a beam that is refracted to 90° from the normal. If the angle of incidence is even more shallow than that, total internal reflection occurs. If you look at the surface of the water in an aquarium from next to the aquarium just below the water's surface, it's just like a mirror. Since the amount of refraction is proportional to the difference between the refractive indexes of the media, much more total internal reflection happens in substances with much higher refractive indexes, like diamonds, accounting for the glistening.

What has the index of refraction of 1.376?
Fill a glass with water. Put a straight rod or pencil into the water at an angle. You see an apparent bend in the straight rad. This is caused by the different indexes of refraction of air and water.
What happens as light moves from one transparent material into a different transparent material?
IF the refractive indexes of the two materials are not the same number, and IF the light is not traveling perpendicular to the boundary between them, then the direction of the light will change at the boundary. This happens because of the slight difference in the speed of light in the two materials. The process is called "refraction" of light. Without it, eyes and other lenses would not work.
What happens when light travels to air to water?
The speed of the light wave slows Some light is reflected off the surface of the water The light that enters the water is "refracted" (the direction of propagation changes due to the different indexes of refraction in air and water) Eventually the water will absorb all the energy of the light if the water is deep enough
What type of stock indexes are there?
There are indexes that cut across industries; there are indexes that deal with one industry only. Indexes include varying numbers of stocks.
How many indexes can be created in a table?
we can create 16 indexes 1 primary index 15 secondary indexes You should not create more than five indexes for any one table because: Whenever you change table fields that occur in the index, the index itself is also updated. The amount of data increases. The optimizer has too many chances to make mistakes by using the 'wrong' index. If you are using more than one index for a database table, ensure that they do not overlap.
What is a good sentence for indexes?
The indexes in the library catalogue help users find the books they need quickly and easily.
When was Dow Jones Indexes created?
Dow Jones Indexes was created in 1882.
