If an electron and a photon propagate in the form of waves having the same wavelength , it implies that they have the same

Options

A. momentum
B. energy
C. velocity
D. angular momentum

Answer

A

Explanation

de - Broglie wavelength is given by
`lambda = (h)/(p)`
where `h` is Planck's constant ,`p` is momentum and `lambda` is wavelength.
Since electron and proton have the same wavelength the momentum of both will be same.
