Question

a ray of light strikes one face of the prism at an angle of incidence of 60° and angle of refraction is 30° if the angle of prism is 60° then the angle of emergence help me I will make u brainy

​

Answer 1

Answer:

normal to the face through which it emerges

Explanation:

Incidence angle an one face of a prism i=60o 

angle of prism, A=30o

deviation angle δ= angle between incident ray and emerent ray =30o

using formula δ=i+e−A

So 30o=60o+e−30o

or e=0

hence angle made by emergent ray with normal to face of plane is 0o.
