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 ______

विकल्प

• `λ = ((2"mc")/"h")""^lambda"d"^2`

• `λ = ((2"h")/"mc")""^lambda"d"^2`

• `λ = ((2"m")/"hc")""^lambda"d"^2`

• `λ_"d" = ((2"mc")/"h")lambda^2`

Answer 1

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 = `underline(λ = ((2"mc")/"h")""^lambda"d"^2)`.
