Webof the photon energy Eto c2 is the inertial mass of a photon. So the inertial mass of a photon is proportional to its energy, and is certainly not zero. So in the case of photons, the situation is extreme. Their rest mass is zero, their inertial mass is not. Clearly the use of both rest and inertial mass in our course is going to be confusing.

WebThe “rest mass” of a photon is meaningless, since they’re never at rest — the energy of a photon E = mc2 = m0c2 √1 − v2 / c2 is of the form 0/0, since m0 = 0 and v = c, so “ m ” can still be nonzero.
