An electron and a photon each have a wavelength of 1.00 nm. Find
the kinetic energy of electron.

An electron and a photon each have a wavelength of 1.00 nm. Find their momenta?

An electron and a photon each have a wavelength of 1.00 nm. Find the energy of the photon?

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.

An electron and a proton have equal momentum. Which has more kinetic energy and what is the ratio between the kinetic energy of electron and proton?

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