Ray of light is incident at an angle of 50° with the surface of glass of refractive index 1.5 find the deviation of ray when it enters glass

Answer»

Dear Brainly member,
Here is your answer:-
A/Q,
angle i = 50 degrees
RI = 1.5
=>sin i / sin R = 1.5
=>sin 50 / sin r = 1.5
=>50/r = 1.5
=>r = 1.5*50
=>r = 75
deviation angle when light ray ENTERS glass = angle of refraction,r = 75 degrees
/ for division and * for multiplication.

Hope it helps. Please MARK my answer as brainliest.
