Question

The photon of frequency vis incident on a metal surface whose threshold frequency is v₀. The kinetic energy of the emitted photoelectrons will be ______.

Options

• hv

• `"hv"_0`

• h `("v" + "v"_0)`

• h `("v" - "v"_0)`

Answer 1

The photon of frequency vis incident on a metal surface whose threshold frequency is v₀. The kinetic energy of the emitted photoelectrons will be ______.

Explanation:

K.E_max = hv - `phi` = hv - hv₀ = h (v - V₀)
