The de Broglie wavelength (λ) associated with a photoelectron varies with the frequency (ν) of the incident radiation as, [ν0 is threshold frequency]:
  1. \(\lambda \alpha \frac{1}{\left(v-v_{H}\right)^{\frac{3}{2}}}\)
  2. \(\lambda \alpha \frac{1}{\left(v-v_{H}\right)^{\frac{1}{2}}}\)
  3. \(\lambda \alpha \frac{1}{\left(\nu-\nu_{\theta}\right)^{\frac{1}{4}}}\)
  4. \(\lambda \infty \frac{1}{\left(v-v_{\theta}\right)}\)

Answer

(B) 1 (v-v_ H )^ 1 2
