Difference between EM wave & a Matter wave ?

 

[CompuChip]

Well, what do you mean by "a matter wave"?
Do you mean, for example, what is the difference between a light wave and a wave in a string?

like we can take example of a tennis ball . Its mass is huge & by de broglie its wavelength is extremely small .

So what is the basic difference b/w EM wave & matter wave ?

So what is the basic difference b/w EM wave & matter wave ?

A mechanical wave travels at a constant speed relative to its medium.

An electromagnetic wave travels at a constant speed relative to the observer.

That is the most significant difference in behavior as I see it.

Electromagnetic waves are also more fundamental. Mechanical waves are emergent phenomena when large numbers of atoms interact. Similar to heat or color, they do not exist on a sufficiently small scale.
