I really like rainbows, because of the pretty colours. There are seven colours in a rainbow, they are red, orange, yellow, green, blue, indigo and violet.
Do you know how a rainbow is formed?
When it rains and it’s sunny at the same time you will see a rainbow form. It happens because the beams of the sunlight separate into colours when it enters the water from the rain. Sunlight is actually made from different colours but we can’t see them as they appear to be white when it reaches the earth. And water can separate the colours, that is why the rainbow is formed when it rains and sunny.
