In physics, a redshift is an increase in the wavelength, and corresponding decrease in the frequency and photon energy, of electromagnetic radiation (such as light). The opposite change, a decrease in wavelength and simultaneous increase in frequency and energy, is known as a negative redshift, or blueshift. The terms derive from the colours red and blue which form the extremes of the vi… WebMay 11, 2024 · Those objects that are furthest away have the highest redshift.

WebJul 8, 2024 · Some stars vary their color, and Christian Doppler thought this was due to their periodic shift with regard to Earth: now we know that that variation was due to temperature. Redshift was later proved to be true: the Earth's movement in its orbit and the relative motions of stars contribute to the change in frequency of the received light.
