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

A

Thermal proton > Visible photon > Thermal electron

B

Thermal proton > Thermal electron > Visible photon

C

Visible photon > Thermal electron > Thermal neutron

D

Visible photon > Thermal neutron > 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.
