If an electron and a photon have the same wavelength, then they will have the same

A

velocity

B

linear momentum

C

angular momentum

D

energy

Text Solution

Verified by Experts

The correct Answer is:

B

When a non-relativistic electron and a non-relativistic proton are moving and have the same de Broglie wavelength , then they will have the same liners momentum p = mv. If the electron and proton have the same momentum, they cannot have the same speed because of the difference in their masses , An electron and photon can have the same wavelength since the wavelength of electron can be changed by changing its velocity .
