Particle-Specific/Light-Specific Equations

Postby Lily Guo 1D » Tue Oct 17, 2017 9:33 pm

In class, Professor Lavelle mentioned that the De Broglie equation can only be used for particles with rest mass, like electrons, and therefore can't be used for light. Are there any other equations that can only be used for particles with rest mass or that can only be used for light?

Th kinetic energy equation (KE = .5mv^2) is the only equation that we've specifically touched on in class that requires an object to have a rest mass. Other than that I don't think we've covered anything else that is mass-dependent yet.
