As a star collapses to produce a black hole,the photons that escape from it

Question

Quizplus · Accepted Answer

As the star collapses, the gravitational force becomes stronger, causing the photons to lose energy, which results in the wavelength of the photons getting longer (i.e., redshifted). This is known as gravitational redshift. The other choices are incorrect as photons cannot move faster than the speed of light, turn into neutrinos, or produce a white hole.
