Answer 1

Answer:

refer the image in above

Answer 2

ANSWER

Let the refractive index of air be μ

a

and that of the glass be μ

g

.

Also let i be the angle of incidence and r be the angle of refraction.

From Snell's law,

μ

a

sini=μ

g

sinr⇒

μ

g

μ

a

=

sini

sinr

As μ

g

>μ

a

⇒sini>sinr⇒i>r

Therefore option A is correct.
