Question

(a) A ray of light falls normally on a face of a glass slab. What are the values of angle of incidence and angle

of refraction of this ray?

(b) Light enters from air to a medium ‘X’. Its speed in medium‘X’becomes1.5× 108m/s. The speed of light in

air is 3x108m/s. Find the refractive index of medium ‘X’.​

Answer 1

Answer:

a) value of angle of incidence and refracted ray is 0°

b) refractive index of medium X

= 3 × 10⁸ / 1.5 × 10⁸

= 2
