What happens to the light from a star that has contracted within its event horizon?

Question

Quizplus · Accepted Answer

When a star contracts within its event horizon, it becomes a black hole. The gravitational force of a black hole is so strong that nothing, including light, can escape it. Therefore, the light from the star that has contracted within its event horizon cannot escape from the region around the star. Choice B is incorrect because nothing can travel faster than the speed of light. Choice C is incorrect because the light cannot escape, so there is no way to determine its frequency or wavelength. Choice D is incorrect because the relationship between wavelength and energy still holds, but the light cannot escape to interact with other matter outside of the black hole.
