Question
When the accelerating voltage applied on the electrons increased beyond a critical value
- Only the intensity of the various wavelengths is increased
- Only the wavelength of characteristic relation is affected
- The spectrum of white radiation is unaffected
- The intensities of characteristic lines relative to the white spectrum are increased but there is no change in their wavelength
The correct answer is: The intensities of characteristic lines relative to the white spectrum are increased but there is no change in their wavelength
