Speed of light changes
WebThe change in direction of the light ray depends on how the speed of light changes. The change in the speed of light is related to the indices of refraction of the media involved. In the situations shown in Figure 3, medium 2 has a greater index of refraction than medium 1. This means that the speed of light is less in medium 2 than in medium 1. WebStep 1: Identify the index of refraction n n for the medium the light is passing through. The index of refraction of glass is n = 1.6 n = 1.6 . Step 2: Calculate the speed of light in the medium v ...

This is the only speed at which photons can move. They can't ever speed up or slow down. ( Note: Photons do change speed when they pass through different materials. This is how refraction occurs, but it's the photon's absolute speed in a vacuum that cannot change.)
