Question

why angle i=angle e​

Answer 1

Answer:

The angle of incidence at this surface is ∠r2. The light ray emerges out of the slab forming ∠e as angle of emergence. Hence, angle of incidence equals angle of emergence.

Answer 2

Explanation:

ANGLE OF INCIDENCE IS EQUAL TO ANGLE OF EMERGENCE BECAUSE IT FOLLOWS THE RULE OF REFLECTION AND AS WELL AS REFRACTION ALSO WE CAN ABLE TO SEE ANGLE OF EMERGENCE IN THE CASE OF REFRACTION WHERE THE ANGLE OF INCIDENCE DEVIATES FROM ITS PATH AND TENDS TO BEND TOWARDS THE NORMAL OR AWAY FROM THE NORMAL DEPENDING UPON THE MEDIAS IT HAS SO WHEN WE DRAW A STRAIGHT LINE TOWARDS WILL GET ANGLE OF EMERGENCE WHICH IS ALWAYS EQUAL TO ANGLE OF INCIDENCE..
