Verified by Experts

1) All the rain drops that discourse the light to fomr rainbow lie within a cone of semivertical angle `40^(@) "to" 42^(@)`
2) If two observers are standing at a distance apart, they will observe rainbow a different parts 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.
