Two observers standing apart from one another do not see the "same" rainbow. Explain

  1. All the rain drops that disperse the light to form rainbow lie within a cone of semi vertical angle 40° to 42°.
  2. If two observers are standing at a distance apart, they will observe different parts of rainbow on the surface of the cone.
  3. So the portion of the rainbow observed by an observer depends on the position of the observer.
  4. Two different observers will form two different cones with the observer standing at the vertex of the cone, therefore rainbow seen by them will be different.
