De Brogile's equation
Can someone explain what Lavelle meant when he said not to use the equation for a photon for questions related to light?

We cannot use the De Brogile's equation for light, because wavelength=h/momentum, and momentum equals mass times velocity. Since photons do not have a mass, momentum would be zero, and we cannot divide by zero.

Re: De Brogile's equation
The equation can only be used for something that has a rest mass. A photon of light does not, and therefore the equation cannot be used.

Re: De Brogile's equation
Photon is quantized electromagnetic radiation. It is a specific amount of energy and thus it does not have mass.
