Statement (S): Monochromatic X-rays fall on lighter elements such as carbon and show scattering under the name of Compton effect.

Explanation (E):

\lambda_{\text {scattered }}

light is always lower than

\lambda_{\text {incident }}

light.

View answer and explanation

Correct option: A

S is correct but E is wrong

Option A is correct because the statement about Compton effect is correct, but the explanation about the wavelength is wrong. In Compton scattering, the scattered wavelength is always greater than the incident wavelength.
