What happens when light travels out of a gravitational field,loses energy,and its wavelength grows longer?
A)a gravitational blue shift
B)the solar wind
C)a gravitational red shift
D)a pulsar wind

Question

Quizplus · Accepted Answer

This is known as a gravitational red shift. As light travels out of a gravitational field, it loses energy and its wavelength grows longer, causing the light to shift toward the red end of the spectrum. This effect is a result of the gravitational field causing a shift in the perceived frequency of the light.
