Maths behind the rainbow | plus.maths.org
2011年10月21日 · Keats complained that a mathematical explanation of rainbows robs them of their magic, conquering "all mysteries by rule and line". But rainbow geometry is just as elegant as the rainbows themselves.
What Do You Know About Rainbows? What is the radius of the rainbow? What is the color sequence in the rainbow? What is the sky darkness and brightness? Is there a second bow? What is the color sequence? Are rainbows polarized? The Rainbow - What Do You See?
The Mathematics of Rainbows - American Mathematical Society
René Descartes, most famous as a philosopher and also as the discoverer (inventor?) of analytic geometry, was responsible for the first detailed study of the rainbow in Europe.

Interactive math video lesson on Rainbows explained: Use refraction to understand rainbows and their features - and more on geometry
rainbow. In the first of the following two diagrams (Figure 1), one finds the Sun setting in the west, rain falling in the east, and an (astonished) observer taking note of the rainbow formed in the sky by the interaction of rays of light from the Sun and droplets of water in the shower. W?! 42 S Figure 1: Observation
The key idea, expressed by Descartes, is that rainbows are formed due to refraction and re ection of sunlight by raindrops. More speci cally, this combination of refraction and re ection occurs stronger at certain an-gles than it does at other angles. We will now explain why this is so.
AMS :: Feature Column :: The Mathematics of the Rainbow, Part II
The Mathematics of the Rainbow, Part II I'll first recall in some detail the steps leading to Airy's formula for the intensity of light in a rainbow, and then say something about how Airy made it possible to compare his theory to experiment...
Rainbow, Great Pyramid, Icosahedron: a Formal Geometric Comparison Curiously, a light deflection angle around 42° is known as the main rainbow angle between the incident sunlight and the refracted and internally reflected light rays within a water drop

2024年12月8日 · The Calculus of Rainbows Rachel W. Hall * Nigel Higson November 30, 1998 Abstract The geometry of reflection and refraction explains the apparent position of a rainbow relative to the sun, and calculus shows why light is concentrated in the rainbow.
Mathematical explanations of the rainbow - ScienceDirect
2011年2月1日 · Explanations of three different aspects of the rainbow are considered. The highly mathematical character of these explanations poses some interpretative questions concerning what the success of these explanations tells us about rainbows.
