### e=hv used for particles?

Can E=hv be used only for electromagnetic radiation? Or can it also be applied to particles?

It is only used for electromagnetic radiation, E= 1/2 (m)(v)^2 is used for particles

E=hv can only be used for Electromagnetic radiation (light). To find the energy for other particles, use the kinetic energy equation: KE=(1/2)mv^2 since other particles have mass. If you want to find the wavelength for light, use λ=c/v; for particles with mass use the De Broglie equation: λ=h/p

E=hv can be used for the energy of a photon, so if you think of light as acting like a particle rather than a wave you can use that equation.
