1 – When hydrogen molecules receives high energy spark the H2 molecules absorb energy and some of H-H bonds are broken. The resulting H atoms are excited (contain excess energy)
2 – The excited atom release energy by emitted light of various wavelengths and produce emission spectrum of hydrogen.
3 – Continuous spectrum: result when white light is passed through prism.
4 – When the hydrogen emission spectrum in the visible region passed through prism we see few lines each line corresponds to certain wavelength. This spectrum called line spectrum.
