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