Two photons having

Question

Two photons having (A) equal wavelengths have equal linear momenta (B) equal energies have equal linear momenta (C) equal frequencies have equal linear momenta (D) equal linear momenta have equal wavelengths

Tardigrade Admin · Accepted Answer

The magnitude of momentum and de-Broglie wavelength are related as

λ = \frac{h}{p}

Therefore if linear momenta are same then wavelengths are equal but if wavelengths are same then only the magnitudes of momenta are same while direction might be different.

Q. Two photons having

equal wavelengths have equal linear momenta

equal energies have equal linear momenta

equal frequencies have equal linear momenta

equal linear momenta have equal wavelengths

The magnitude of momentum and de-Broglie wavelength are related as λ=ph​ Therefore if linear momenta are same then wavelengths are equal but if wavelengths are same then only the magnitudes of momenta are same while direction might be different.

The magnitude of momentum and de-Broglie wavelength are related as
$λ = \frac{h}{p}$
Therefore if linear momenta are same then wavelengths are equal but if wavelengths are same then only the magnitudes of momenta are same while direction might be different.
