Question

In an experiment to trace the path of a ray of light passing through a rectangular glass slab, four students tabulated their observations as given below:which is the correct observation Immersive Reader (1 Point) ∠i 30° ,∠r18,°∠e 32° ∠i 30° ,∠r20,°∠e 32.5° ∠i 30° ,∠r17,°∠e 30° ∠i 30° ,∠r21.5,°∠e 34.5°​

Answer 1

angle i = 30°

Angle r = 17°

angle e = 30°

because angle of incidence has to be equal to the angle of emergence.

I hope it helps
