Light travels through a substance at 1.97 x 10^8 m/s. What is the index of the liquid? What type of liquid is it?

The refractive index of the liquid is 1.52. The substance is a crown glass.

Explanation:

Given:

Velocity of light through the substance, v = 1.97 X 10⁸ m/s

Refractive index of the liquid, μ = ?

We know,

μ =

where, c = velocity of light in air

            v = velocity of light in the substance

speed of light in air is 3 X 10⁸m/s

Therefore, refractive index of the liquid is 1.52. The substance is a crown glass.

n = 1.52

Index of the liquid = 1.52

The type of the liquid is Crown glass.

Explanation:

In finding the index of refraction, we use this formula

n = c/v

where n is the index of refraction

c is velocity of light in vacuum which is constant and is equivalent to

v is the velocity of light in a particular medium

Here we use

Using the formula,

n = c/v

n =

n = 1.52284264

n = 1.52

Thus, the index of the liquid is 1.52
