Question

Is a spectral line with wavelength 656 nm seen in the absorption spectrum of hydrogen atoms? why or why not?

Answer 1

No, Photons are absorbed in a quantum jump from a lower energy level to a higher energy level.

When an electron moves closer to the nucleus and emits a photon, to move an electron further from the nucleus requires the absorption of a photon.

A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from absorption of light in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules.
