A ray of light falls on a denser-rarer boundary from denser side. The critical angle is `45^(@)`. The maximum deviation the ray can undergo is

A

`30^(@)`

B

`45^(@)`

C

`90^(@)`

D

`120^(@)`

Text Solution

Verified by Experts

The maximum deviation can be, when it is reflected bact at
`I = theta_(C ) = 45^(@)`
`therefore` Deviation, `delta=180^(@)-2i=90^(@)`
