Also find the de-Broglie wavelength of a neutron, in thermal equilibrium with matter, having an average kinetic energy of `3/2 KT` at 300 K.

What is the de-Broglie wavelength of an electron with kinetic energy of 120 eV?

The de-Broglie wavelength of a photon is the same as the wavelength of electron, show that kinetic energy of photon is (2mclambda)/h times the kinetic energy of electron, where m is the mass of electron and c is the velocity of light.

The de-Broglie wavelengths,associated with a proton and a neutron,are found to be equal.Which of the two has a higher value for kinetic energy?

Obtain the de-Broglie wavelength of a neutron of kinetic energy 150 eV. As you have seen in Q.NO.11.31, an electron beam of this energy is suitable for crystal diffraction experiments. Would a neutron beam of the same energy be equally suitable? Explain (m_n=1.675xx10^-27) .

Determine the de-Broglie wavelength of a proton, whose kinetic energy is equal to the rest mass energy of an electron. Given that the mass of an electron is 9.1 xx 10^(-31) kg and the mass of a proton is 1,837 times as that of the electron.

What is the momentum and De Broglie wavelength of an electron with kinetic energy of 120 eV.
