    You are a brilliant teacher. That initial illustration of refraction is great. I hope you can lead me to victory on Monday.

    I'm using your videos for GCSE revision. They actually go into enough detail for me to understand the whole concept, unlike most of the GCSE books and channels.

    Woah that analogy of refraction in the beginning! Genius!

    Okay so I had a question. Yk the second equation for n? In that equation, will the speed in the less denser medium always be the numerator, or will the numerator be the speed in whatever medium the ray is in first?
    Great video by the way, I loved the analogy!

    Hi there, do you have any videos explaining the critical angle? Thanks, good work on your videos by the way, there are many A level physics videos but I rarely come across any that aren't boring so thanks :)

    3:34 Isn't snells law --> sin(i)/sin(r) = n(r)/n(i) and not = n?

    • @lolagepwned
      @lolagepwned 6 років тому

      Bishop Baptu I think you're right, but it's typically used from air- something else, where the n of air is basically 1

    • @gracewebb2692
      @gracewebb2692 4 роки тому

      the n he's talking about is the combined refractive index of the two materials, which is n(r)/n(i)
