Question

Which one of the following parameters of the emitted X-rays increases when the potential difference between the electrodes of an X-ray tube is increased?  

Solution

Correct option is

Frequency

If V is increased, the energy of X-rays E = eV also increases. But E = hv. Hence frequency v is increased.
