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
In an atom, two electrons move around the nucleus in circular orbits of radii $R$ and $4R.$ The ratio of the time taken by them to complete one revolution is : (neglect electric interaction)
