An X-ray tube operates at 40 kV. Suppose the electron converts 70% of its energy into a photon at each collision. Find the lowest three wavelengths emitted from the tube. Neglect the energy imparted to the atom with which the electron collides.

An X-ray tube operates at 20 kV. A particular electron loses 5% of its kinetic energy to emit an X-ray photon at the first collision. Find the wavelength corresponding to this photon.

An X-ray tube is operated at 30 eV. If a particular electron loses 10% of its kinetic energy to emit an X-ray photon during the collision. Find the wavelength and maximum frequency assoicated with this photon.

Consider the electron energy level diagram of H-atom Photons associated with shortes and longest wavelength would be emitted from the atom by the transitions labeled

The wavelength of a photon is 1.4 Å . It collides with an electron. Its wavelength after collision is 2.0 Å . Calculate the energy of the scattered electron.

An X-ray tube operating at 50kV converts 1% energy in the form of X-ray. If the amount of heat produced is 495 watt, then the number of electrons colliding with the target per second is

An X-ray tube operates at 10kV. Find the ratio of X-rays wavelength to that of de-broglie wavelength associated with incident electron.
