Statement I: A lighr ray is incident on a glass slab. Some portion of it is reflected and some is refracted. Reeefracted and reflected rays are always perpendicular to each other.
Statement II: Angle of incidence is equal to angle of reflection.

A

STATEMENT -`1`is true statement `2` is true,Statement -`2`is a correct explanation for statement -`1`

B

STATEMENT -`1`is true statement `2` is true,Statement -`2`is a not a correct explanation for statement -`1`

C

Statement -`1`is true,Statement -`2`is False

D

Statement -`1`is False ,Statement -`2`is True

Text Solution

Verified by Experts

The correct Answer is:
D
`1xx sini =sin r`
`=sin(90-i)`
`sin i=cos i`
`rArr tan i=mu`
So relected and reflected rays are perpendicular if tani=.
