A thin prism of refracting angle `2^@` deviates an incident ray through an angle of `1^@`.Find the value of refractive index of material of prism.

Explanation

To find the refractive index of the material of the prism, we can use the formula for the deviation caused by a thin prism. The formula is:

\[ \text{Deviation} (D) = (\mu - 1) \times A \]

where:
- \( D \) is the angle of deviation,
