A proton and electron have same K.E.Which one has greater de-Broglie wavelength and why?

An electron and an alpha particle have the same kinetic energy. How are the de-Broglie wavelengths associated with them related?

Ana-particle and alpha - protonare accelerated through same p.d. The ratio of de Broglie wavelength of a proton to a-particle is given by

Explain what do you understand by the de Broglie wavelength of an electron. Will an electron at rest have an associated de Broglie wavelength? Justify your answer.

The kinetic energy of an electron is 500 eV. Calculate the de-Broglie wavelength associated with it.

An electron and a proton have the same de-Broglie wavelength . Then the kinetic energy of the electron is

A proton , a neutron , an electron and an alpha -particle have same energy. Then their de Broglie wavelengths compare as

An electron, a proton, α -particle and a hydrogen atom are moving with the same kinetic energy. The associated de-Broglie wavelength will be longest for

A photon, an electron and a uranium nucleus all have the same wavelength.The one with the most energy

An electron, a proton, an alpha-particle and a hydrogen atom are moving with the same kinetic energy.The associated de Broglie wavelength will be longest for
