Electron kept in an enclosure at temperature T have a de broglie wavelength `lamda` . If the temperature of the enclosure is increased , then the de broglie wavelength of the electrons will

A

1. Increase

B

2. Decrease

C

3. Not change

D

4. Be doubled

Text Solution

Verified by Experts

The correct Answer is:
B
`E prop T " and " lamda prop 1/sqrtE therefore lamda prop 1/sqrtT`
`therefore lamda` is decreased.
