### Which equations can be used for what topics

This isn't specific to indeterminancy, but can someone list which equations are allowed to be used for photons and which can be used for electrons?

You can use c=(lambda)(nu) for electromagnetic radiation, or light.
You can use lambda=h/p or lambda=h/mv for electrons because they have mass.

E=hv is used for the energy of a photon, or in this case, electromagnetic radiation.
