  • i still dont get it ...:/

  • I LUV IT THANK YOU

  • This is amazing, easy to understand, great explanations. You have saved my life.

  • Excellent! I'm using this video with my french pupils attending science in english.

  • An hour with a Physics book = 10:03 min with Youtube

  • The most thorough video on the basic theory of refraction I have seen.

    Excellent

  • gud videoo!

  • Thanks, this video includes everything I was looking for. I will use this for my physics lesson next week.

  • @SpykoXX exactly

    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

  • @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

    does that sound about right?
