Question

9.A ray of light strikes a glass slab making an angle of incidence is equal to 45 degree. what will be the angle of emergence? *​

Answer 1

Answer:

If the angle of incidence and angle of emergence of a light ray falling on a glass slab are given then by applying Snell’s law we can get,

Hence the angle of incidence is equal to the angle of emergence = 45°

Answer 2

Answer:

Explanation:

angle of emergence = 50°

since angle of incidence is equal to angle of emergence
