Question

Which of the following correctly describes how light will be affected as it tries to escape from a massive

object like a neutron star?

A) Light doesnʹt have mass; therefore, it is not affected by gravity.
B) The light will be blueshifted.
C) The light will be redshifted.
D) The visible light will be redshifted, but higher frequencies, such as X‐rays and gamma rays, will not be
affected.

Answer 1

Light escaping from a massive object like a neutron star will be redshifted.

Step-by-step explanation:

Light is affected by gravity when trying to escape from a massive object like a neutron star. The correct answer is C) The light will be redshifted. When light travels in a strong gravitational field, its wavelength is stretched, causing it to shift towards the red end of the spectrum. This is known as gravitational redshift. The effect is observed in visible light as well as higher frequencies like X-rays and gamma rays.
