    DOUBT/ATTENTION:-
    Sir, when you were explaining the second step of rainbow formation, you said that Total Internal Reflection will take place at that moment. But for instance, if the light ray that entered from atmosphere(Air) to the raindrop is made to retrace its path then it is evident that the light ray entered at such an angle which is less than critical angle. So, angle of refraction would be be less than critical angle consequently. As a result T.I.R here won't take place. Partial Internal Reflection will take place in this context. Is this right?

    Q) The force exerted on a current carrying wire placed in a magnetic field is zero when angle between the wire and the direction of magnetic field is ?
    Doubt:-
    >If direction of Magnetic field and Flow of current is same direction then angle will be 0°
    Sin 0° = 0
    AND
    >If direction of Magnetic field and flow of current in opposite direction the angle will be 180°
    Sin 180° = 0
    {Sir then which angle would be more appropriate to write in exam.}
    Please help.

    • @prt4691
      @prt4691 3 роки тому

      Brothy Both of them are correct
      You should that's why specify the direction
      If you write that direction of magnetic field and current is same
      Then take 0°
      And if you take opposite direction
      Then take angle 180°
      Also you can show both the possibilities
      As you have written here 👍

    Dispersion of white light by a glass prism: The phenomenon of spliting of white light into
    its seven constituent colours when it passes through a glass prism is called dispersion of
    white light. The various colours seen are violet, Indigo, Blue, Green, Yellow, Orange and
    Red. The sequence of colours remembers as VIBGYOR. The band of seven colours is called
    the spectrum. The different component colours of light bends at a different angle with respect
    to the incident angle. {{{***The violet light bends the least while the red bends most.***}}}
    this is that line
