What fills the sky with light but isn’t a star?

What only appears when it is raining?

What is a symbol of Hope, Equality, and Good Luck?

It’s a Rainbow!

A rainbow is produced by a ray of light being REFRACTED and reflected by water.

Light is refracted (bent) as it enters a water droplet. It is then REFLECTED (bounced off) the back of the droplet. As the reflected light exits, it is refracted again. 

The ELECTROMAGNETIC SPECTRUM is made of light with many different wavelengths, and each is reflected at a different angle. Thus, the spectrum is separated, producing a Rainbow.

In fact, there are numerous types of Rainbows that undergo different processes in their formation.

Have you ever seen six

 rainbows at once? 

These rainbows are in the rainfall, and the light is coming from behind the spectator. The main rainbow is the one with the most vibrant color. The secondary rainbow, which appears above and to the left of the main rainbow, is the result of many internal reflections within water droplets.

Supernumerary Rainbows

Supernumerary rainbows are formed as sunlight strikes small droplets of water, usually having a diameter not exceeding 1 millimeter. One distinct feature of supernumerary rainbows is that they are made up of pastel colors instead of the normal spectrum present in the usual rainbow.

MONOCHROME RAINBOW 

Known as a red rainbow, a monochrome rainbow is a rare weather-related occurrence and only happens when sunlight travels farthest through the earth’s atmosphere, during sunrise or sunset.
