Moonbows

A moon bow is also known as the lunar rainbow or the space rainbow. It is a rainbow produced by the light reflected off the moon instead of the normal rainbows which happens due to sunlight. They are much rarer and generally appear more faint and white even due to the light from the moon being very faint. These moonbows are most easily viewed during the full moon when the moon is the brightest. Spray moonbows are where the moonbows are formed not from the rain but from sprays from waterfall. A place that spray moonbows can be seen often would be Yosemite National Park in California.

Rainbows are formed due to the concept of refraction. The water droplets acts as a prism, which Sir Isaac Newton used to show that white light consisted of different colors, where when the light enters, the lights are dispersed due to the individual wavelengths of the colors in white light, making the rainbow have its five pure colors. For example, blue light has a shorter wavelength then the red light. As such, it would be refracted at a greater angle. However, the light is still reflected at the back of the droplet, making the blue light emerge from a smaller angle than the red light.

The Concept behind the Rainbow

Rainbows

A rainbow is an optical phenomenon that can be seen when light is refracted when it passes through water droplets from either the moisture of the Earth or the rain. It can also be formed by passing through mist, sprays and airborne dew. It is a multicolored arc made out of seven colors: red, orange, yellow, green, blue, indigo and violet. Despite being known for seven colors, rainbows actually only have five pure colors, orange and indigo being produced due to the crossing of the red and yellow and the blue and violet light rays respectively. Rainbows can be seen anywhere so long there is water droplets in the air as well as sunlight to provide the light to pass through. It can even be created by using a hose or a water spray which scatters water,

There are actually different types of rainbows apart from the usual single arc rainbow. Below are the two of the many types Secondary Rainbow it appears frequently outside the primary rainbow and are caused by double reflection of sunlight inside raindrops. Due to the double reflection, the colors are inverted.

Supernumerary Rainbow It is a phenomenon where several rainbows are formed on the inner side of the normal single arc rainbow which the rainbow to have over seven layers and the colors do not follow the usual order of red, orange, yellow, green, blue, indigo and violet.
