A ray is incident at an angle `38^@` with a mirror. The angle between normal and reflected ray is ........... .

`52^@`

`38^@`

`90^@`

`70^@`

Text Solution

Verified by Experts

The correct Answer is:

A, B

From figure,
i+`38^@=90^@`
`therefore i=52^@`

From the law of reflection,
angle of reflection = angle of incident
`therefore r=i`
`therefore` r=`52^@`
