Solution

The correct option is D Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
The relationship between the wavelength of a moving photon and its mass is $λ = \frac{h}{m u}$ .
The above equation is rearranged to obtain $∴ m \propto \frac{1}{λ}$ .

Thus, Mass of moving photon varies inversely with wavelength.

The relationship between the energy of particle wave and the mass is given by the Einstein's relationship.

Energy of particle wave $= m a s s \times (s p e e d o f l i g h t)^{2}$ or $E = m c^{2}$

Thus, Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
