If we consider electrons and photons of same wavelength, then they will have same (a) momentum (b) angular momentum (c) energy (d) velocity

Answer: (a). For both photons and electrons, λ = h/p. Same λ gives the same momentum p = (h)/(λ); energy and speed differ. So the answer is (a) momentum.

Matter Waves: de Broglie Wavelength

If we consider electrons and photons of same wavelength, then they will have same

Show answer and solution

Answer: (a)

For both photons and electrons, $\lambda = \dfrac{h}{p}$ .
Same $\lambda$ gives the same momentum $p = \dfrac{h}{\lambda}$ ; energy and speed differ.
So the answer is (a) momentum.
