A gas of monoatomic hydrogen is bombarded with a atream of electrons that have been accelerated from rest through a potential difference of 12.75 V . In the emission spectrum, one can observe lines of

Calculate the de Broglie wavelength of an electron that has been accelerated from rest through a potential difference of 5000 volt.

An electron initially at rest is accelerated through a potential difference of one volt. The energy gained by the electron is

A sample of hydrogen gas in its ground state is irrdation with photon of 10.2eV energies The radiation from the above the sample is used to irradiate two other the sample of excited ionized He^(+) and excited ionized Li^(2+) , respectively . Both the ionized sample absorb the incident radiation.
