Rainbow. Part of the arc of a rainbow seen over hills at sunset. Concentric bands of light in the colours of the spectrum are seen. This phenomenon occurs when the Sun is located behind the observer and the sky is filled with raindrops. The separation of colours of light is caused by the reflection and refraction of the Sun's rays in the water drops. The larger the drops,the brighter are the colours.
