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&#8217;s eye.<\/p>\n<p>The rainbow is caused by the refraction of light in the water droplets. When sunlight hits a water droplet, it is refracted (bent) as it enters the droplet. The light is then reflected off the back of the droplet and refracted again as it exits the droplet. The angle of refraction depends on the wavelength of the light, which is why we see a spectrum of colors in the rainbow.<\/p>\n<p>The primary rainbow is the brightest and most common type of rainbow.
