El efecto Doppler: variación de frecuencia por movimiento

The video tutorial explains the concept of wave movement, focusing on how an observer perceives changes in frequency, particularly with acoustic waves. It uses the example of a moving train to illustrate how frequency variation affects pitch. The tutorial also extends the concept to light waves, explaining how the toppler effect helps deduce the speed and direction of distant stars and galaxies.

In what way can we measure the Doppler effect of light from distant stars?

What can we deduce about distant stars and galaxies by measuring the Doppler effect?
