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

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

What is the momentum of an electron of energy 100 eV?

Obtain de-Broglie waveelngth of an electon of kinetic energy 150 eV.Given mass of electron, m=9.1 xx 10^(-31) kg ,charge on electron, e=1.6 xx 10^(-19) C and Planck's constant , h=6.62 xx 10^(-34) J s .

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.

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) .
