Question

While tracing the path of a ray of light passing through a rectangular glass slab the angles of incidence are 40 and 50. Find angle of emergence and angle of refraction?

Answer 1

For i = 40°

r = 28.9

e= 40°.

For i = 50°,

r =35.2

e = 50°

Answer 2

Answer:

angle of emergence is 45 degree
