Question

The angle of incidence in air for a ray of light is 40 . If the ray travels through water of refractive index 4/3 . Then the angle of refraction is

Answer 1

points to note before solving:-

1. incident ray shift towards the normal when going from rarer to denser medium due to decrease in speed of the light
2. incident angle is measured from the normal

put the value of sin40° you will get the answer...!!!

hope it helps..

Good luck ♧♧
