In a photoelectric experiment, a graph is drawn with stopping potential along Y -axis and the frequency of the incident light along X -axis. If the graph is a straight line which makes an angle with Y-axis, then = (h-planck's constant, e-charge of electron)

Options

  1. Ah e
  2. Be h
  3. Ch e
  4. De h

Correct answer

A. h e

Step-by-step solution

From the photoelectric equation aligned & eV _ s = hv - & V _ s = hv e - e aligned By compairing above equation with y = mx + c slope = m = = h e
