H-alpha line is a red visible spectral line in hydrogen atom with a wavelength of 656.3 nm. Consider five distant stars labeled A, B, C, D, and E. The light from these starts was detected on Earth and, after performing spectral analysis, the following H-alpha wavelengths were measured: = 668.3 nm, AB 655.1 nm, Ac 653.2 nm, Ap = 663.6 nm, and AE 662.4 nm.
