why is the rainbow always seen in the form of a arc or semicircle?? |

Answer» It only involves sunlight, water, and your eye. So there\'s no reason that the Earth being flat or curved ought to change the shape of a rainbow. The reason a rainbow is circular is that a circle is the set of all points in the sky that make the same angle between you, the water droplets, and the sun. But why is the rainbow circle? A rainbow is not actually shaped like a semicircle or an arc; that is simply the shape that we see. In fact, a rainbow is a circle, but we can’t see the full shape because the horizon cuts off the lower half. However, if you were flying high enough, without any disturbance, then you would be able to see a full rainbow. |
