The potential difference applied to an X-ray tube is increased. As a result, in the emitted radiation,

Options

A. The intesity increases
B. The minimum wavelength increases
C. The intensity decreases
D. The minimum wavelength decreases

Answer

D

Explanation

For an X - ray tube , `lamda_("min") = (hC)/(eV) " or " lamda_("min") prop 1/V`
`therefore` if V is increased, `lamda_("min")` is decreased.
