MCQ
Two photons having:
- AEqual wavelengths have equal linear momenta.
- BEqual energies have equal linear momenta.
- CEqual frequencies have equal linear momenta.
- ✓Equal linear momenta have equal wavelengths.
✓
Answer
Correct option: D.
Equal linear momenta have equal wavelengths.
Two photons having equal linear momenta have equal wavelengths is correct. As in the rest of the options magnitude of momentum or energy can be same because energy and momentum are inversely proportional to wavelength. But the direction of propagation of the photons can be different.
