### de Broglie vs electromagnetic radiation

How do you know when to use the De Broglie equation or the equations for electromagnetic radiation like E=hV

I think debroglis is used if you want to find wave length and E=hv is used if you have frequency or energy and want to find the missing variable.

E=hv is used only in regards to electromagnetic radiation since it uses constant c (the speed of light) while De Broglie is used for any other particle that has momentum since its velocity is variable.

You would use de Broglie's to find the wavelength (or describe wave properties) of an object that has resting mass (not light), and you would use E=hv to find the energy of a photon (light).
