1

What is angle of refraction?

angle that transmitted ray makes withe perpendicular plane of if interface between two media

2

What does index of refraction tell us?

how much slower light travels through that medium than through empty space

3

What is index of refraction equal to?

speed of light in a vaccuum divided by speed of light in a medium

4

If n2 is greater than n1, which way will ray bend?

toward the middle of medium. N2 angle is smaller

5

If n2 is less than n1, which way will ray bend?

away from the middle of medium. N2 angle is greater

6

What is total internal reflection?

Case where incident ray energy will be reflected back to the original medium and there is no refracted ray

7

Under which case will total internal reflection occur?

the angle of incidence is greater than the critical angle. high index to low index

8

If angle of incidence is equal to critical angle

refracted beam skims the boundary

9

True or falseElectromagnetic waves travel at different speeds when traveling through a material medium like glass or water

True

10

Do colors of higher frequencies bend more or less upon entering medium?
