### equation conversions

I've seen the equation for the energy of a photon joined with the debroglie equation but I never understood how. Can someone explain how they can be put together?

I have not seen this before. The DeBroglie equation cannot be used for light, so I'm not sure if it can be applied or combined with the equation for the energy of a photon?

It is a general rule that some equations cannot be used for light, and I think this may be one of the cases.
