Question

refractive index of benzene is 1.50 . what does it mean?​

Answer 1

Answer:

Refractive index of benzene = 1.50. We know : Speed of light = 3 × 10⁸ m / sec. We know formula for n : n = speed of light in vacuum / speed of light in benzene.

Answer 2

Answer:

Refractive index of the benzene (μ)=1.50

Initially, the light was traveling in the air.

After traveling in air, the light enters benzene.

Let the velocity of the light in benzene=v

Then,

Refractive index of the benzene,

So,

The change in velocity of light

=c−v

=3×10

Hence,

The percentage of reduction in speed will be
