In an experiment to study photoelectric effect the observed variation of stopping potential with frequency of incident radiation is as shown in the figure. The slope and y -intercept are respectively

Options

  1. Ah e ,- h v₀ e
  2. Bh v e , v₀
  3. Ch v e ,- h e
  4. Dh v₁-h v₀

Correct answer

A. h e ,- h v₀ e

Step-by-step solution

The maximum kinetic energy of emitted photoelectrons is given as array ll & e V₀=h v- ₀ & V₀= ( h e ) v- ₀ e array Comparing with y=m x+c , we get aligned m & = h e and c=- ₀ e =- h v₀ e Slope & =m= h e aligned
