What is the speed of light moving through a medium of index of refraction 2.45?

To determine the speed of light in a medium with a given refractive index, you can use the formula:

Speed of light in a medium = Speed of light in vacuum / Refractive index

The speed of light in vacuum is a well-known constant, approximately 299,792,458 meters per second (m/s).

In this case, the refractive index of the medium is given as 2.45. Plugging these values into the formula, we can calculate the speed of light in the medium:

Speed of light in a medium = 299,792,458 m/s / 2.45

By performing the calculation, we find that the speed of light through a medium with an index of refraction of 2.45 is approximately 122,442,481 meters per second (m/s).
