2. The increase in wavelength of electromagnetic radiation emitted by an object moving away from an observer, as explained by the Doppler effect
Astronomers use red shift measurements to calculate the velocity of receding stars.
Os astrônomos usam medições de desvio para o vermelho para calcular a velocidade das estrelas que se afastam.
Red shift is a fundamental concept in modern astronomy and cosmology, widely discussed in both American and Brazilian scientific communities. The term is essential for understanding the Big Bang theory and the expanding universe model, which are cornerstones of contemporary physics education in both countries.
