In the glass slab experiment, a student measures the angle of incidence `(angle i)` in air and finds it to be `40^(@)`. He also measured the corresponding angle of refraction as well as the angle of emergence for this ray of light but also their record. The most likely record of readings for the angle of incidence and angle of emergence wil be :

Options

A. `angle r = 40^(@)` and `angle e = 50^(@)`
B. `angle r gt 40^(@)` and `angle e = 50^(@)`
C. `angle r = 50^(@)` and `angle e = 40^(@)`
D. `angle r lt 40^(@)` and `angle e = 40^(@)`

Answer

D
