Question

1.a ray light AB is incident on a glass slab show value of angle of incidence and angle of refraction for the ray of light?

2.light enter from air into a glass plate having refractive index 1.5?

Answer 1

A ray of light is incident on a glass slab at an angle of 45°. If the refractive index of glass will be 1.6, then what is the angle of refraction?

How does the DuckDuckGo app/extension protect my privacy?

It is 26 degree because n=sin i/sin r

n=1.6

1.6=sin 45/sin r

sin r=(1/root 2)/1.6

sin r=10/23

sin r=0.43

therefore,r=26 degree

Answer 2

1- pls tell the angle at which it felt
