Using the Doppler effect, so-called spectroscopic double stars were discovered. For these stars, the spectral lines periodically become double, from which we can conclude that the source is two stars orbiting their center of mass. In the spectrum of one such star, the largest distance between the components of the periodically bifurcating hydrogen line with a wavelength of 434.047 nm is 0.053 nm. Find the orbital velocity of the stars that make up the binary source, projected onto the line of sight.
