Question

a ray of light passing through a thin prism suffers a deviation 2°30'.if the refractive index of the prism is 1.5. Find the refracting Angle​

Answer 1

Answer:

A light ray passing through a thin prism suffers a deviation δ . Now the prism is cut into two halves symmetrically in the vertical direction. The deviation for the same ray will be

Explanation:

δ=(μ−1)A

After cutting it vertically the angle becomes

2

A

So, δ

1

=(μ−1)

2

A

=
