At temperatureT, the average kinetic energy of any particle is32kT. The de Broglie wavelength follows the order:

Options:

Answer:
A
Solution:

λn=h2mE
(E=kTfor thermal neutron)
λn=h2mnkT=30.835T=30.83517.32=1.78 
λe=150V
Kinetic energy for electron in hydrogen atom=13.60 eV V=13.6 V
λe=15013.6=3.32 
λphotonvisible range=6000 
λphoton>λelectron>λneutron
