What phenomenon causes light waves from a receding star to stretch toward the red end of the spectrum?
Answer
Cosmological redshift.
When a star recedes due to the expansion of the universe, the light waves traveling from it are stretched. This stretching shifts the light toward the red end of the spectrum, a phenomenon known as cosmological redshift.
