Statement-I: Two photons having equal linear momenta have equal wavelengths.
Statement-II: If the wavelength of a 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.
a. Statement-I is false but Statement-II is true
b. Both Statement-I and Statement-II are true
c. Both Statement-I and Statement-II are false
d. Statement-I is true but Statement-II is false
Energy of photon
E = hc / λ
= E ∝ 1 / λ
Hence, energy of photon increases as the wavelength of light decreases. Also, momentum of the photon p = E / c
⇒ p ∝ E
Thus, momentum of the photon also increases as its wavelength decreases.
