1.	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 FalseD. Statement -`1`is False ,Statement -`2`is True
Answer» Correct Answer - 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=.
