Question

What are matter waves ? I have not understand the topic clearly. Please help me.

Answer 1

See answer here. In case you need more information feel free to contact.

Explanation:

It is possible to calculate de Broglie wavelength for anything, using the following expression

de Broglie wavelength `lambda = h/p`
where `h` is Planck's constant `=6.626xx10^-34" J"cdot"s"`, and
`p` is the momentum of the object.

It may be seen that objects with large mass or having large velocity, `lambda` is very very small.
