Question

(a) () What is a matter wave ? Calculate the
wavelength associated with a body of
mass 1-5 g moving with a velocity of
100 ms--​

Answer 1

Answer:

Matter waves are a central part of the theory of quantum mechanics, being an example of wave–particle duality. All matter exhibits wave-like behavior. For example, a beam of electrons can be diffracted just like a beam of light or a water wave. ... Matter waves are referred to as de Broglie waves.
