Any mention of something that has a mass (electrons, protons, neutrons, etc) will use DeBroglie's Equation, while any light/photons will NOT, because they do not have mass.
You will use the De Broglie equation in most quantum questions when the question asks for either the momentum, frequency, or wavelength of an electron. If you given any 2 of these variables, you can find the other using wavelength=h/mv. You can also find the energy of an electron using this equation and Planck's equation: E=hv.
You use de broglie’s equation to find the wavelength of anything that is not light and has a mass since mass is involved in the equation. Examples of these would be protons, electrons, and ions.
