If a spaceship approaches you at 0. 5c, and a light on the spaceship is turned on pointing in your direction, how fast will the light be traveling when it reaches you?

The light will be travelling at its own speed 300,000 km/s which is the speed of the light.

Speed of light:

One universal physical constant that is significant in many branches of physics is the speed of light in a vacuum, typically abbreviated as c. Its precise value is 299792458 meters per second or roughly 300000 kilometers per hour or 186000 miles per hour. The maximum speed at which common matter, energy, or any signal carrying information may move through space is c, according to the special theory of relativity.

Similar to how electromagnetic waves in wire cables move more slowly than c, light moves more slowly through transparent materials like glass or air. The refractive index n of a substance (n = c/v) is the ratio between c and the speed v at which light moves through it.
