EM Radiation and DeBroglie Equation

Postby DTingey_1C » Sun Oct 20, 2019 7:07 pm

Since the DeBroglie equation requires a momentum to work, how does EM radiation have a wavelength? I thought light was massless, so how would it have a momentum that could be plugged into the equation?

i don't think theres a consensus about that, it's a weird property of light to have momentum but not mass. Heres an article that I read online: http://www.desy.de/user/projects/Physic ... _mass.html

Thank you so much for sharing this, I'd been wondering about this myself :)
