In case of photoelectric effect, slope of V 0 vs ν curve is (where V 0 - stopping potential, ν = subjected frequency)

Options

  1. Ae
  2. Bh e
  3. Cϕ
  4. Dh

Correct answer

B. h e

Step-by-step solution

ω = ω 0 + eV 0 ...(1) ω = work function ω 0 = threshold energy hν = hν 0 + eV 0 V 0 = hν 0 e − hν 0 e ...(2) ν = subjected frequency ν 0 = threshold frequency Comparing equation (2) with straight line equation: y   =   mx   +   c Slope of ν 0 v/s ν curve = h e
