The wavelength of light the spectral emission line of sodium is 589 nm. Find the kinetic energy at which (a) an electron and (b) a neutron,would have the same de Broglie wavelength.

The wavelength of light from the spectral emission line of sodium is 589 nm. Find the kinetic energy at which a neutron, would have the same de-Broglie wavelength.

If photon and an electron have same de-Brogile wavelength then.

For what kinetic energy of a neutron will the associated de-Broglie wavelength be 1.40 xx 10^-10m ?

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

Light of wavelength 500 nm falls on a metal whose work function is 1.9 eV. find the kinetic energy of the photo electrons emitted.

Select the correct option: If an electron and a photon have smae de Brogile wavelength, then they will habe same:

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.

Two particles A_1 and A_2 of masses m_1 , m_2(m_1>m_2) have the same de-Broglie wavelength then
