What Is a Matter Wave?

[J-Girl]

Could anybody give me a good definition of what a matter wave is? I am studying electromagnetic waves for my final exam, and unsure of the definition! I looked it up on the net a few times but it wasn't direct at all. Thankyou!:)

At a guess, I think this probably refers to the wave-particle duality of matter, as opposed to sound waves traveling through a material.

De Broglie (pronounced 'de Broy') showed us that particles can behave like waves in the same way that light can. He said that the kinetic energy (E) of these particles is equal to Planck's Constant (h) multiplied by the wave frequency (f); E = hf
