How does the gravity of an object affect light?
A)Light doesn't have mass;therefore,it is not affected by gravity.
B)Light coming from a compact massive object,such as a neutron star,will be redshifted.
C)Light coming from a compact massive object,such as a neutron star,will be blueshifted.
D)Visible light coming from a compact massive object,such as a neutron star,will be redshifted,but higher frequencies such as X-rays and gamma rays will not be affected.
E)Less energetic light will not be able to escape from a compact massive object,such as a neutron star,but more energetic light will be able to.

Question

According to general relativity, the gravity of a massive object can cause light to redshift, meaning that the wavelength of the light increases as it moves away from the source of gravity. This effect is known as gravitational redshift, and it has been observed in light coming from compact massive objects such as neutron stars.
