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

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

  1. A

    Thermal proton> Visible photon> Thermal electron

  2. B

    Thermal proton > Thermal electron > Visible photon

  3. C

    Visible photon > Thermal electron > Thermal neutron

  4. D

    Visible photon > Thermal neutron > Thermal electron

    Solution:

    Kinetic energy of any particle=32KT

    Also K.E.=12mv2

    12mv2=32KT v=3KTm

    De-broglie wavelength

    =λ=hmv λ=h3KTm λ α 1m

    mass of thermal neutron > mass of thermal electron > mass of visible photon

    order of debroglie wavelengths is Visible photon > Thermal electron > Thermal neutron
