    Difference between school physics teachers and Organic Chemistry Tutor
    Teachers teach you definitions, formulas, laws
    Organic Chemistry Tutor not only teaches you the three above but also teaches you where it came from and how things work.
    Excellent 10/10 channel on YT
    Improved my physics grades by rocket speed.

  • @David-uy7ev
    @David-uy7ev Před 2 lety +7

    I believe you've made a mistake in the problem with light passing through air, glass and diamond (around 20:00). When calculating the final angle you used sin(35.26), whereas I believe it should be sin(57.74), which is the angle between the normal line and the light. You would then get an angle of 30.69 instead of 21.1. Please correct me if I'm wrong.

    • @joseenricoaguila5218
      @joseenricoaguila5218 Před 2 lety

      right

    • @joseenricoaguila5218
      @joseenricoaguila5218 Před 2 lety

      he misplaced the 35.26 which is supposed to be an incident angle. so it's still sin(35.25) to be used.

    • @tykhonpuhach9496
      @tykhonpuhach9496 Před 8 měsíci

    • @tykhonpuhach9496
      @tykhonpuhach9496 Před 8 měsíci

      No, actually, he has a point. The new angle of incidence is equal to the old angle of refraction, because these are two angles with parallel lines and a secant in the form of a reflected ray.

    To find Theta 3, dont you have to use the complementary angle of Theta 2, in order to use properly the Snell's law?

    • @eduardomoreira7624
      @eduardomoreira7624 Před 2 lety

      If you’re talking about the angle about the normal line of the refraction light then no you do not. Theta 2 (reflection) = theta 1(incident) and theta 3 can just be solved using the formula n1sin(theta1)=n3sin(theta3)

    • @eduardomoreira7624
      @eduardomoreira7624 Před 2 lety

      The numbers are interchangeable so it can be considered angle 1,2, or 3 as long as you know the difference in each and know how to apply them in each formula

    • @eduardomoreira7624
      @eduardomoreira7624 Před 2 lety

      Actually if you’re talking about 20:15 then yes you are right I think he made a mistake

    • @eduardomoreira7624
      @eduardomoreira7624 Před 2 lety

      Never mind I saw what he did , it’s because it’s the opposite angle that is equal

  • @St37One
    @St37One Před 2 lety +1

    I was really hoping to find a formula which relates the index of refraction, or the change in the speed of light on the one hand to the wavelength or the frequency of the light on the other hand. Obviously, different frequencies/wavelengths of light diverge in a prism due to this principle, but what is the mathematical formula that allows you to predict the degree of bending or slowing by knowing the frequency or wavelength?

  • @bhaven6408
    @bhaven6408 Před 3 lety

    oh my god this guy has everything

  • @jonnyreverb
    @jonnyreverb Před 4 lety +2

    @06:53 So close. The wavelength does not change. Different wavelengths refract at different angles. Refraction does not change colors, just the angle they are deflected. You cannot put a red laser into a prism and get a blue laser out (unless it's a KTP or BBO crystal, but that's another can of worms).

    • @nostestwu8689

    • @kutukutilk
      @kutukutilk Před 6 lety +3

      If you used alternate angles, then you should get around 54.74° which is incorrect as it is not specified if it's a parallel line.

    • @wccrowley
      @wccrowley Před 6 lety +3

      I'm wondering the same thing. I don't follow the reasoning of the replies you've received either.
      His initial process involves relating angles between the ray of light and the "normal line". Then he switches for the second calculation to using the angle between the ray of light and the surface to find the third angle.

    • @patrickrosborough2247

    Why didn't you use the angle of incidence for the second step of the second example problem? Shouldn't the final equation be 1.5sin(90-35.26)=2.4sin(theta)

  • @leonardobarrera2816

    I'm fairly sure you got one of your practice questions wrong, in the question that light travels from air to glass to diamond. Shouldn't the intercept angle from glass to diamond be 90-35.26= 54.72? As that is the angle from the normal line 20:14

    or you could take the density of air and the density of glass and calculate the difference in speed of light. by deviding c by density. that will give you the refraction. taking into consideration the gravity the air is subject to. as diluted .
