How must light travel out of a substance if it is not going to be refracted?
Draw diagrams to show the refraction of light from glass to air. In diagram, label the incident ray, refracted ray, the angle of incidence (i) and the angle of refraction (r).

Which colour of light travels fastest in any medium except air?
Name the phenomenon responsible in the following case:
Twinkling of stars
State the factors on which the angle of deviation depends.
Trace a ray of light incident at 30° on a surface if travelling from glass to air. What is the angle of refraction in this case? (R.I. for glass = 3/2).
A coin placed at the bottom of a beaker appears to be raised by 4.0 cm. If the refractive index of water is 4/3, find the depth of the water in the beaker.
