Question 179: Dual Nature of Matter and Radiation

Question

Given below are two statements : Statement I : Two photons having equal linear momenta have equal wavelengths.Statement II : If the wavelength of photon is decreased, then the momentum and energy of a photon will also decrease.In the light of the above statements, choose the correct answer from the options given below.

Accepted Answer

As we know, $$\lambda  = {h \over p} = {h \over {\sqrt {2mK} }}$$
If linear momenta of two photons are equal, then their wavelengths is also equal.
Also, if the wavelength is decreased, then the momentum and energy of photon will increase.
Hence, option (d) is correct.
