Question

in a narrow wave packet of matter waves​

Answer 1

Answer:

We have seen how particles behave as waves in quantum mechanics. A wave packet is a form of wave function that has a well-defined position as well as momentum. ... Thus wave packets tend to behave classically and are easy (and fun) to visualize.

Answer 2

In a narrow wave packet of matter waves :

• A wave packet is like a cross between a flyspeck ( single flyspeck) and a wave.
• Describable by a superposition of numerous sine-like swells (this is the Fourier metamorphosis or packet in k space).
• But the numerous swells aren't to be interpreted as numerous patches, just numerous countries for one flyspeck.
