| Part of a pencil that is placed in a glass of water appears bent in relation to the part of the pencil that extends out of the water. What is the phenomenon called? | refraction |
| Refraction is the bending of a wave disturbance as it passes at an angle from one _____ into another. | glass |
| Which is an example of refraction? | A fish appears closer to the surface of the water than it really is when observed from a riverbank. |
| The _____ of light can change when light is refracted because the velocity changes. | wavelength |
| When a light ray passes from water (n=1.333) into diamond (n=2.419) at an angle of 45 degree, its path is | bent toward the normal |
| When a light ray passes from air into glass, which has a higher index of refraction, its path is | bent toward the normal |
| A ray of light in air is incident on an air-to-glass boundary at an angle of exactly 30.0 degree with the normal. If the index of refraction of the glass is 1.65, what is the angle of the refracted ray within the glass with respect to the normal? | 18.0 degree |
| A lapidary cuts a diamond so that the light will refract at an angle of 17.0 degree to the normal. What is the index of refraction of the diamond when the angle of incidence is 45.0 degree? | 2.4.2 |
| What type fo image does a converging lens produce? | real or virtual |
| All of the following images can be formed by a converging lens exactly except which one? | real, upright, and magnified |
