NEET 2017 Physics de-Broglie Wavelength MCQ Question
Type: MCQ-conceptual-Medium-Class 12
The de-Broglie wavelength of a neutron in thermal equilibrium with heavy water at a temperature T (Kelvin) and mass m, is:
A
h/√mkT
B
h/√3mkT
C
2h/√mkT
D
h/√mkT
Correct Answer
Option B
Detailed Explanation
The de-Broglie wavelength is calculated using the formula λ = h/p, where p is the momentum. For thermal equilibrium, p is related to temperature.
