please answer for class 8

Answer 1

Answer:

ray of light passes through an equilateral glass prism such that the angle of incidence is equal to the angle of emergence and each of these angles is equal to 3/4 of angle of prism. ... Angle of deviation for a ray of light in a prism is given by, Prism is an equilateral triangle.
