### 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.

I think it can be only used for energy of photon.

My understanding is that it is only applicable to photon energy for electromagnetic waves.

You can only use it for light because the v in E=hv refers to frequency, which most large particles do not show.

Can some one explain to me how to utilize avagrado's number? Is it usually utilized as a conversion for photons are there other ways to use this number?

Avagrado's number is used when working with moles, so what the professor taught Week 1. For E=hv, the constant that is used is Plank's constant.

E=hv is only usable for electromagnetic radiation.
