Question

An electromagnetic wave of wavelength 'λ' is incident on a photosensitive surface of negligible work function. If 'm' mass is of photoelectron emitted from the surface has de-Broglie wavelength λ_d, then :

(1) λ = \((\frac{2m}{hc})λ^2_d\)

(2) λ_d = \((\frac{2mc}{h})λ^2\)

(3) λ = \((\frac{2mc}{h})λ^2_d\)

(4) λ = \((\frac{2h}{mc})λ^2_d\)

Answer 1

Option : (3) λ = \((\frac{2mc}{h})λ^2_d\)
