Question

A ray of light travelling from
air enters a liquid at an angle
of 45° with the normal. If the
corresponding angle of
refraction is 30°, then the
refractive index of the liquid
with respect to air is
1.44
1.41
O 1.21
1.45​

Answer 1

Answer:

1.414

Explanation:

Sin 45 =1/ (2 ^(1/2))

Sin 30 = 1/2

So, refractive index of liquid wrt air is

1.414
