  • Problems involving the refraction of light

    Total internal reflection can take place only when the ray travels from a denser medium to a rarer one. As medium 1 is rarer than medium 2, total internal reflection cannot take place at the boundary of medium 1 and 2. 5. False.

  • Intersection of planes

    This can be understood properly by an example -- the best example is three mutually perpendicular axes (X,Y,Z) which form three mutually perpendicular planes (XY, YZ and ZX), they meet at one point that is at the origin.
