Determining Redshift via Astronomical Spectroscopy

, 2018
The Doppler effect is a well-known physical phenomenon which results in a change of a wave’s frequency or wavelength due to the motion of its source. Celestial objects in space (stars, galaxies, etc.) also experience a Doppler effect on their emitted electromagnetic radiation called redshift. In this study, redshifts were observed in the spectrographic
