Question

X: The refractive index of a medium depends on its nature
Y:The refractive index of a medium depends on the wave length of the light used
A) Both X and Y are right
B) X is right, Y is wrong
C)X is wrong, Y is right
D) Both X and Y are wrong​

Answer 1

Answer:

C) X is wrong, Y is right.

Explanation:

Refractive index of a medium is the Speed of light in vaccum to speed of light in that medium.

Further, Speed is the product of frequency of light and wavelength.

Therefore, the refractive index of a medium depends on the wavelength of the light used.
