ANSWER

If the angle of incidence and angle of emergence of a light ray falling on a glass slab are given then by applying Snell’s law we can get,

sinr

sini

=

n

1

n

2

sine

sinr

=

n

n

1

On multiplying the above two equation we get

sine

sini

=1

sini=sine

Hence the angle of incidence is equal to the angle of emergence
