A hydrogen gas-filled discharge tube was activated with one election and one proton, hydrogen is the simplest element and gives the simplest line spectrum There
are only four lines in the visible region of the hydrogen spectrum, 656 nm (red), 486 nm (blues
green), 484 nm blue violet), and M14 nm (violet)
However, it was observed that there was a fifth line in the spectrum of hydrogen. What could be the reason for this
The hydrogen gas used was ionized,
The gas used had traces of another element
The diffraction gradient distorted the spectrum
The disintegration of the emitted photons of energy
