Question

are matter waves electromagnetic
​

Answer 1

Answer:

There are some characteristics of matter wave which are as follows: Matter waves do not depend on the charge on particle thus is not of electromagnetic nature. ... The wavelength does not depend upon the nature of the particle. The wavelength will be smaller if the moving speed of the particle is more.

Answer 2

Answer:

Matter waves do not depend on the charge on particle thus is not of electromagnetic nature. The De-Broglie wavelength depends on the weight of the particle, so, less the weight, more will be the wavelength. The wavelength does not depend upon the nature of the particle.
