A ray of light, in air, strikes one side of a rectangular glass block. The refractive index

Question:

A ray of light, in air, strikes one side of a rectangular glass block. The refractive index of the glass is 1.5.

a. Draw a diagram to show the direction the ray will take in the glass if the angle of incidence is 0°.

b. Draw a diagram to show the approximate direction the ray will take in the glass if the angle of incidence is 45°, and calculate the angle of refraction.

c. If the speed of light in air is 3 x 10⁸ m/s, calculate the speed of light in the glass.
