Question

Please answer-


A boy uses blue colour of light to find the refractive index of glass. He then repeats the experiment using red colour of light. Will the refractive index be the same or different in the two cases ? Give a reason to support your answer.​

Answer 1

Explanation:

Refractive index will be different in these two cases i.e., \mu_B > \mu_Rμ

B

>μ

R

(In glass).

Reason: In glass, speed of red light is greater than speed of blue light.

Answer 2

Answer:

Hope it clears...

Explanation:

Refractive index of glass is different for different colours. The speed of blue light is less than red light. So, the wavelength of blue light is less than that of red light. Thus, the red light would deviate less than blue light because of difference in wavelength..
