At temperature T , the average kinetic energy of any particles is `(3)/(2)` kT. The de Broglie wavelength follows the order :

A

Thermal proton gt Visible photon gt Thermal electron

B

Thermal proton gt Thermal electron gt Visible photon

C

Visible photon gt Thermal electron gt Thermal neutron

D

Visible photon gt Thermal neutron gt Thermal electron

Text Solution

Verified by Experts

The correct Answer is:
C
The wavelength of the visible photon will be higher than that of thermal electron.
Out of electron and neutron having same energy, the de-Broglie wavelength of electron will be higher because of lower mass of electron.
