If an electron and a photon have the same wavelength, then they will have the same

Calculate the frequency and energy of a photon having wavelength 4000 Å

An electron in the first excited state of H atom absorbed a photon and further excited. The de broglie wavelength of the electron in this state is found to be 13.4 Å. Find the wavelength of the photon absorbed by the electron in angstroms. Also find the longest and the shortest wavelength emitted when this electron de-excited back to the ground state.

What is the work function of a substance if photoelectrons are just ejected for a monochromatic light of wavelength lamda = 3300 Å (answer in eV) ?

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

These ions lose electrons to form stable positive ions.
