Question
The energy and momentum of an electron are related to the frequency and wavelength of the associated matter wave by the relations
But while the value of A is physically significant, the value of v (and therefore, the value of the phase speed v λ) has no physical significance. Why?
Solution
For a moving particle,
De-broglie wavelength is given by,
p is momentum.
Energy of a photon is, E=
Therefore,
Energy of a moving particle =
From the above relation we can see that, has no direct significance on relation of E and p.
