Have you ever seen a rainbow? On rainy day when the sun comes out, a beautiful rainbow appears. Rainbows only appear when it is raining, and the sun is shining. Rainbows are actually beautiful rays of color from the sun. Sunlight look white, but it’s really made up of different colors... red, orange, yellow, green, blue, indigo and violet. When sunlight passes through rain drops, it makes a rainbow. The raindrops act like tiny prisms, and the light spreads out into a band of colors in the shape of a rainbow. Rainbows make everyone happy.
1. We can see a rainbow when the sun comes out on a rainy days.
