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