    Hi sir, I really want to thank you for all your videos on summarizing the Cambridge IGCSE Physics chapter. Thanks to you, I was really able to understand all the different concepts I struggled with. I used to hate Physics just because of how difficult it is but you and my current physics teacher have helped to understand and love physics. I am an extended student, and I had no idea about the addition of digital and analogue waves to the Waves chapter. Thank you for shedding some light on this subject.

    I still don’t understand about the rays bending towards and away from the normal

    • @hamzasalmann
      @hamzasalmann Рік тому +3

      Basically, a normal is a line perpendicular, or starts at the point in which the incident ray HITS the area, in the phenomenon of refraction. Then, the ray changes its speed since its going towards a denser medium, and the change in speed also results in change in direction.
      Since its goes into a denser medium, it goes towards the normal; and when the ray fully aligns itself with the normal, a 'normal incidence' phenomenon occurs, which we havent read yet lol. SO, when its out of the medium, it goes back to its default state.
      And so since it is in its default state, it does not need to go on the way to the normal; and that results in going against / away from the normal and back to its pace.
      Hope this makes sense! :)

    i thought deeper water are denser compared to shallow water

    • @easyart722
      @easyart722 4 місяці тому

      No there’s just more pressure, basically if you take water from a deep pool and bring it out, it will still be same density. This is because density is =mass over volume :) and all materials /substances have only 1 density so water density is a constant
