NEET 2013 Physics de-Broglie Wavelength MCQ Question
Type: MCQ-conceptual-Medium-Class 12
The de-Broglie wavelength of neutrons in thermal equilibrium at temperature T is:
A
3.08/√T Å
B
0.308/√T Å
C
0.0308/√T Å
D
30.8/√T Å
Correct Answer
Option A
Detailed Explanation
The de-Broglie wavelength λ is given by λ = h/p, where p is the momentum. For thermal neutrons, p is proportional to √T, leading to λ ∝ 1/√T.
