Blueshift is defined as the increase in frequency and therefore, a decrease in the wavelength of source with respect to the observer. It is called Blue because in the visible spectrum blue color has the highest frequency and hence low wavelength.
Blueshift is used to determine the velocities with which the galaxies and stars are moving.
