Helium Spectrum
The above are the spectral lines of helium. Which of the following statements is correct about these lines?
a) These spectral lines confirm that the Rutherford's atomic model is correct.
b)These spectral lines mean that the electron of a helium atom has a quantized energy level.
c) The light that has the highest energy level in these spectral lines has a wavelength of nm.

choice a is wrong because rutherford theory only talk about hydrogen spectrum. choice c is wrong . lets see energy= (nhc)/wavelength . the greater its wavelength,the smaller its energy
