Question

In the experiment to trace the path of a ray of the light through a glass slab.

a. if the angle of incidence is increased how does the angle of refraction change.b.what relationship students work out when they measure the angle of incidence and angle emergence

Answer 1

Hey Friend,

In the experiment to trace the path of a ray of the light through glass slab -

a] It is observed that the angle of refraction (r) increases with the increase in the angle of incidence (i)
angle of incidence is directly proportional to the angle of refraction.

b] It is observed that the angle of incidence (i) is equal to the angle of emergence (e)
Due to experimental errors, the angles may not be same but are nearly or approximately equal.

Hope it helps!
