Photoelectric EffectHard
Question
The potential difference applied to an X-ray tube is increased. As a result, in the emitted radiation,
Options
A.the intensity increases
B.the minimum wavelength increases
C.the intensity remains unchanged
D.the minimum wavelength decreases
Solution
As the potential difference is increased, the kinetic energy is increased. The total energy of x-rays emitted will also increase hence intensity will increase. Also the shorter wavelengths will also decrease.
