The speed of light does not decrease when it moves from one medium to another. The speed of light in vacuum, which is approximately 3.00 x 10^8 meters per second (or about 186,282 miles per second), is considered the maximum speed of light. Light may appear to slow down when it passes through a medium other than vacuum, such as water or glass, but its actual speed does not decrease. It is the interaction between light and the atoms or molecules in the medium that affects its apparent speed.
