Solution
neither by an electric field nor a magnetic field
Since X-rays do not have any charged particles, they are not deflected by an electric field or a magnetic field.

The stopping potential in a photoelectric experiment is linearly related to the inverse of the wavelength (1/λ) of the light falling on the cathode. The potential difference applied across an X-ray tube is linearly related to the inverse of the cutoff wavelength (1/λ) of the X-ray emitted. Show that the slopes of the lines in the two cases are equal and find its value.
