When a light wave leaves a region of strong gravity, compared to the same wave leaving a spaceship in empty space, the wave in strong gravity will have

Question

Quizplus · Accepted Answer

When a light wave leaves a region of strong gravity, it experiences a gravitational redshift. This phenomenon is a result of the general theory of relativity and implies that the light's wavelength becomes longer, its frequency becomes lower, and it loses energy as it climbs out of the gravitational well. Thus, all of the statements A, B, C, and D are correct descriptions of what happens to the light wave, making E the correct choice.
