A rainbow is a semi-circular colour spectrum appearing in the sky due to the result of refraction and multiple reflections of sunlight in droplets of water. Rainbows appear when water droplets are lit by direct sunlight, a condition that rarely occurs ''during'' a storm, because the clouds block the sun. Rainbows are frequently seen ''after'' a storm, when the falling rain has moved into the distance and the sun is roughly behind the observer when the observer is facing the patch of rain.

According to [[Genesis]] 9:11-17, after the Flood [[God]] told [[Noah]] that henceforth the rainbow would remind God and Mankind of God's promise never to flood the [[Earth]] again.<ref>Genesis 9:11-17, "And it shall come to pass, when I bring a cloud over the earth, that the bow shall be seen in the cloud: And I will remember my covenant, which is between me and you and every living creature of all flesh; and the waters shall no more become a flood to destroy all flesh."</ref> Physics can explain the appearance of rainbows accurately as the result of refraction and multiple reflections of sunlight in droplets of water, but not the feelings of awe and spirituality rainbows inspire, as they did in [[William Wordsworth]] when he wrote:
