Doubling the momentum of
A)a particle doubles its relativistic total energy.
B)a particle quadruples its relativistic total energy.
C)a photon doubles its relativistic total energy.
D)a photon quadruples its relativistic total energy.

Question

Quizplus · Accepted Answer

Doubling the momentum of a photon doubles its relativistic total energy because both the energy and momentum of a photon are directly proportional to its frequency (or inversely proportional to its wavelength). Therefore, if the momentum is doubled, the energy also doubles, following the relationship E = pc for photons, where E is energy, p is momentum, and c is the speed of light.
