Question

Given below are two statements : Two photons having equal linear momenta have equal wavelengths. 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.

• A. Both Statement I and Statement II are true
• B. Statement I is false but Statement II is true
• C. Both Statement I and Statement II are false
• D. Statement I is true but Statement II is false

Answer 1

Answer: (D)

Statement I is true but Statement II is false

Answer 2

If linear momentum are equal then wavelength also equal
$p =\frac{ h }{\lambda}, E =\frac{ hc }{\lambda}$
On decreasing wavelength, momentum and energy of photon increases.
