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.

Text Solution

Verified by Experts

Here, `A = 2^(@), delta = 1^(1), mu = ?`
As prism is thin, therefore, `delta = (mu -1)A`
`1 = (mu - 1)2, mu = 1 + (1)/(2) = (3)/(2) = 1.5`
