What Causes Rainbows?

A rainbow is a meteorological phenomenon that results from the scattering of light by water droplets. These light particles travel across the sky and form a circular arc. The rainbow is multicolored and is known as the ‘eye of God’. Learn what causes rainbows. Interested in astronomy? Then, read our article on the dispersion of light. You’ll learn about its size, auxiliary rainbow and color.

Dispersion of light

Rainbows are a beautiful example of dispersion. This phenomenon is caused by the fact that the white light of the sun is divided into seven different colors by a prism or water droplet. When white light passes through the prism or water droplet, it bends and changes its propagation direction. The angle of refraction varies with wavelength and color. The lower the wavelength, the smaller the angle of refraction.

Size of raindrops

We’ve all seen rainbows, but do you know why they’re so big? There are two main reasons. First, raindrops have different sizes because their surfaces are not all the same size. It’s not like the spheres in our brains, where the size is a function of mass. Second, raindrops are formed from particles of varying sizes, and this translates to a wider variation in the sizes of rainbow raindrops.

Size of auxiliary rainbow

Auxiliary rainbows are useful when modifying a particular color. Generally, you can use more than one fixing map for the same colour, but this is pointless. The last numbered fixing map determines the colour, while the earlier ones are ignored. Adding auxiliary axes multiple times will produce multiple aux axes of the same colour. Besides, multiple auxiliary axes will allow you to create more than one coloured ray.

Colors of rainbow

You may have heard of the rainbow. This meteorological phenomenon occurs when the light that is emitted by a drop of water reflects off another drop of water. The result is a spectrum of light in the sky that takes the form of a circular arc. There are many different colors in the rainbow, so it’s important to know what causes it and why you might see one. Here’s an explanation:

Perception of rainbows

The perception of rainbows depends on the way one sees them. The colour perception of a rainbow is based on the way our eyes lie in alignment with the different hues of the spectrum. When we look at the Sun, the white light of the Sun is converted into different hues as the raindrops pass by. Higher raindrops appear redder, whereas lower ones are blue. These differences in color make it possible for a rainbow to appear.

Size of tertiary rainbow

The size of a tertiary rainbow is about ten times larger than a quaternary one. It was first observed and photographed in rain. Its incredible size and shape sparked scientific curiosity. But the question remains: why is it so large? What can it tell us about the nature of the rainbow? It might also reveal information about the Earth’s past. If you are wondering, here are some possible explanations.

Shape of tertiary rainbow

A rare type of rainbow called the tertiary is found over Kampfelbach in Germany, about 40 degrees from the Sun. This is the result of triple reflections inside raindrops. As its name suggests, the shape of a tertiary rainbow is oblong or triangular in shape. This phenomenon may have been a long-time predicted by meteorologist Raymond Lee, who taught at the U.S. Naval Academy.

Location of tertiary rainbow

A rare optical phenomenon, a tertiary rainbow has a unique shape because of the three reflections of each light ray in a raindrop. Photographic persistence and a new meteorological model have confirmed this unusual phenomenon. This new phenomenon is described in the special issue of the journal Applied Optics. But how do you spot this rainbow? Here are some tips to locate it:
