Question

Refractive indices of ice benzene ruby and kerosene in which of the above media light travels slowly

Answer 1

Refractive indices of Ice, Benzene, Ruby and Kerosene are 1.31, 1.50, 1.71 and 1.44 respectively. In which of the above media, light travels showly ?

Answer:

The following media light travels slowly is Ruby

Explanation:

The refractive index is the degree of bending of a mild ray while passing from one medium to another. It also can be described because the ratio of the rate of a mild ray in an empty area to the rate of mild in a substance, n = c/v.

Refractive index for a medium may be defined as the ratio of speed of light in vacuum to the speed of light in that particular medium. Refractive index is a pure ratio and hence it do not have a unit.

n= speed of the light in vaccum / speed of the light in medium

n$\alpha$1/Sm

1.71>1.5>1.44>1.31

Ruby>benz>kerosene>ice

The following media light travels slowly is Ruby

Answer 2

Light will travel slowly in Ruby.

Given: Refractive indices of ice = 1.31,  ruby = 1.71,  benzene =1.50  and kerosene = 1.44

To find: In which media light travels slowly.

Solution :

Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another.

Refractive index for a medium may be defined as the ratio of speed of light in vacuum to the speed of light in that particular medium.

It can be described as,

n = speed of light in vacuum / speed of light in medium.

Speed of light in vacuum is constant, and hence, n is inversely proportional to speed of light in medium.

1.71 > 1.51 > 1.44 > 1.31

Value of refractive index, n, is highest in ruby. Hence, speed of light in ruby is slowest among the given media.

Hence, ruby is the correct answer.
