The speed of light in glass – it’s the same, trust me [mith]

Guess you already knew that. But many don’t know that the speed of light in transparent materials is the same, but strange things happen as we measure that it is, in fact,… slower. Now what’s that?

Well, it’s true and false. Yes, the speed of light is the same, when we see the light as wave and then as particle, but it takes more time to cross the transparent material (glass) because it bounces back and forth from the atoms in that material. Now you’re coming back.

Watch an inspiring educational movie by Minute Physics. So, let’s get Physics-cal at light speed.
