Options

  1. AThe number of photoelectrons emitted for light of a frequency v (higher than the threshold frequency v_0 ) is
  2. BThe number of photoelectrons emitted for light of a frequency v (higher than the threshold frequency v_0 ) is
  3. CThe number of photoelectrons emitted for light of a frequency v (higher than the threshold frequency v_0 ) is
  4. DThe number of photoelectrons emitted for light of a frequency v (higher than the threshold frequency v_0 ) is

Correct answer

A. The number of photoelectrons emitted for light of a frequency v (higher than the threshold frequency v_0 ) is

Step-by-step solution

de-Broglie's wavelength, λ=hp\lambda = \dfrac{h}{p}
⇒pλ=h⇒ p\lambda = h
⇒\lambdap=h⇒ \lambdap = h, Same as \left(xy = c\right)<br/>Momentum,<br />Momentum,p ∝ \dfrac{1}{\lambda} (Rectangular hyperbola)
Which of the following figures represent the variation of particle momentum and the associated de-Broglie wavelength?
