I love rainbows, they're so pretty. It's hard to believe that it is caused by water bending light sometimes.
A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets 
Yep it sure it, I couldn't remember that many details though lol. I really do like how the gay people have taken it to be their symbol too. 
Uhmnn,never knew it was used as a symbol. However the water droplets resulting in a spectrum of light appearing in the sky
Do you know why we never see the bottom of the rainbow? 
Well,I believe it could be as a result of the Atmospheric optics which deals with how the unique optical properties of Earth's atmosphere 
Oh cool. DO you know of any other phenomena that are caused by the refraction of light? 
rainbow is caused by light being refracted when entering a droplet of water, then reflected inside on the back of the droplet and refracted again 
Right, but what about double rainbows?
primary rainbow, the arc shows red on the outer part and violet on the inner side. This rainbow is caused by light being refracted when entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it.
In a double rainbow, a second arc is seen outside the primary arc, and has the order of its colours reversed, with red on the inner side of the arc. This is caused by the light being reflected twice on the inside of the droplet before

A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.
Rainbows can be full circles. However, the observer normally sees only an arc formed by illuminated droplets above the ground, and centered on a line from the sun to the observer's eye.
