i haven't finished watching this all the way through yet but doesn't the theory of relativity state that light will always go at 300000000 meters per second relative to everything? however this video talks about working out the speed of light through a transparent substance how can this be?
We know that glass is made of atoms, well when a light beam hits a glass what happens at the atom level is, the first atom that encounters the light beam absorves, oscillates and then produce another light beam, which will do the same process on the adjacent atom until it exits the glass.
In some object this process of absorbing, oscillating and remitting light is quite faster than other thus slowing the "speed" of the light as it travels through the object.
@eddieonofre i see so whenever it is a beam of light it is in fact travelling at the speed of light but the time between when one beam is absorbed and the second beam of light is created gives the illusion of slowing light and all that is really being worked out is the time it takes for a photon to enter the transparent substance and the time it takes to leave
different atoms take more time to recreate the photon they absorve thus making the average speed of light through the material slower and it bends (refracts) the light as well
i still dont get it ...:/

does that sound about right?

when i do the sine of 27.22 i get 0.4574
(approx 03.26 in the video) not 0.4594 as in the video
im trying to learn this stuff ,
is it a mistake or am i doing something wrong?
