Question

Assertion : As light travels from one medium to another, the frequency of light does not change.Reason : Because frequency is the characteristic of source.​

Answer 1

Assertion : As light travels from one medium to another, the frequency of light does not change.

Reason : Because frequency is the characteristic of source.

BOTH ASSERTION AND REASON ARE TRUE AND REASON IS THE CORRECT EXPLANATION OF ASSERTION.

First of all, when light travels from one medium to another, we call the phenomenon as REFRACTION.

• During refraction, light gets deviated from its path because of change in velocity due to corresponding change in wavelength.

• However, the frequency of the wave doesn't change. Because the frequency of the wave is determined by the source and not the medium through which it is flowing.

So, both A and R are correct, and Reason correctly explains Assertion !
