Double Rainbow


My Mom used to tell me that a rainbow was God's way of telling us his promise to never flood the earth again like he did with Noah.
.
But what Mom forgot to tell me is that a double rainbow is a double reflection of sunlight inside the raindrops, and appear at an angle of 50°–53°. As a result of the second reflection, the colours of a secondary rainbow are inverted compared to the primary bow, with blue on the outside and red on the inside.
