Options

  1. A18 %
  2. B25 %
  3. C20 %
  4. D32 %

Correct answer

B. 25 %

Step-by-step solution

K ₂=(1-0.36) K ₁=0.64 ~K ₁ De-Broglie wavelength of the particle is aligned & = h 2 mk 1 k & ₂ ₁ = K ₁ ~K ₂ = k ₁ 0.64 k ₁ =1.25 & ₂=1.25 ₁ aligned % increase in de-Broglie wavelength is % = ₁ 100= 1.25 ₁- ₁ ₁ 100=25 %
