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.

1. Both Statement I and Statement II are true
2. Statement I is false but Statement II is true
3. Both Statement I and Statement II are false
4. Statement I is true but Statement II is false

Correct answer: Statement I is true but Statement II is false

Solution

Statement I is true because photons with equal linear momenta must have the same wavelength, as momentum is directly related to wavelength. Statement II is false because decreasing the wavelength of a photon actually increases its momentum and energy, contrary to the claim.
