Question

The refractive index of water is 1.33 and that of kerosene is 1.44. If a ray of

light enters from the air into the water and from the air into the kerosene, it

will get more refraction in __________​

Answer 1

Required Answer:-

Refractive index is the measure of how fast a light ray travels through the medium. Given,

• Refractive index of water = 1.33
• Refractive index of kerosene = 1.44

Clearly, refractive index of kerosene is more than that of water. Kerosene is more optically denser than water. Hence, it will get more refraction in kerosene (Answer).

Refractive index(μ) is the ratio of speed of light in air/vaccum to speed of light in the medium i.e. c/v. Hence, we can say that it is indirectly proportional to the speed of light in the medium$.$

• Refractive index more, Bending more...

It is because speed of light is more in rarer medium and less in denser medium.

Answer 2

Answer:

Required Answer :-

$\rule{303}{5}$

In this question there is two refractive index of water and kerosene.

Refractive index of water = 1.33

Refractive index of kerosene = 1.44

We can clearly see that the kerosene has more refractive index.

Hence, The correct answer is Kerosene.

The formula for refractive index is

ng = c/v

ng is the refractive index

c is the speed of light in air/vaccum space.

v is the speed of light in glass
