Which of the following physical quantities have the same value for electron and photons of same wavelength?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Momentum
De-Brogle wavelength (λ) is -
$λ=\frac{h}{P}$ [P = Momentum]
$⇒λ_{electron}=λ_{photon}$ [Given]
$⇒\frac{h}{P_{electron}}=\frac{h}{P_{photon}}⇒P_{electron}=P_{photon}$
