If electron beam in a Coolidge tube is accelerated by 100 volt and targeted on high atomic number (z > 30) material. What will be spectrum of energy emitted?
Options:
Answer:
B
Solution:
At 100 eV the electrons are far below the keV binding energies of inner shells, so no characteristic X-rays. lies in the ultraviolet. Only a continuous spectrum, mainly in the ultraviolet and visible region, is emitted.
