Critical angle of glass is theta(1) and ...

Critical angle of glass is `theta_(1)` and that of water is `theta_(2)`. The critical angle for water and glass surface would be `(mu_(g)=3//2, mu_(w)=4//3)`

A

less than `theta_(2)`

B

between `theta_(1)` and `theta_(2)`

C

greater than `theta_(2)`

D

less than `theta_(1)`

Text Solution

Verified by Experts

The correct Answer is:
C
As `.^(w)mu_(g) = 9//8 lt .^(a)mu_(w) lt .^(a)mu_(g) :. theta gt theta _(2) gt theta_(1)`
