The Brewsters angle ib for an interface ...

The Brewsters angle `i_b` for an interface should be:

A

`30^(@) lt i_(A) lt 45^(@)`

B

`45^(@) lt I_(b) lt 90^(@)`

C

`i_(b) = 90^(@)`

D

`0^(@) lt i_(b) = 30^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
`tan I_(b) = (mu_(2))/(mu_(1)) = (mu_(2))/(1)`
`mu_(2) gt 1`
`therefore tan_(b) gt 1`
`therefore 90^(@) gt I_(b) gt 45^(@)`
