From the figure shown, establish a relation between `mu_1,mu_2,and mu_3`

A

`mu_1ltmu_2ltmu_3`

B

`mu_3ltmu_2,mu_3=mu_1`

C

`mu_3gtmu_2,mu_3=mu_1`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
Between 1 and 3 there is no deviation. Hence,
`mu_1=mu_3`
Between 3 and 2

Ray to light binds towards normal. Hence,
`mu_2gtmu_3.`
