Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The relation between the refractive index (n) and speed of light in a medium (Vm) is ____ proportional.

A	directly
B	inverlsely
C	Either A or B
D	None of the above

Explanation:

Detailed explanation-1: -Hence, the refractive index of a medium is inversely proportional to the speed of light in that medium. Q. More the refractive index of a medium, more is the speed of the light in that medium.

Detailed explanation-2: -Light slows down if the refractive index of a medium increases, because the speed of light in a medium is inversely proportional to the refractive index of the medium, i.e., n ∝ 1/v.

Detailed explanation-3: -From the equation n = c/v, we know that the refractive index of a medium is inversely proportional to the velocity of light in that medium. Hence, light travels faster in water.

Detailed explanation-4: -Refractive index is directly proportional to wavelength.

Detailed explanation-5: -Wavelength of light is directly proportional to the refractive index. Refractive index is inversely proportional to the wavelength of light.
