Why is the sky blue?
Earth's atmosphere contains small gas molecules and dust particles. Sunlight entering the atmosphere meets the gas molecules and dust particles. Color rays that have longer light waves such as red and yellow, can pass through and penetrate the gas and dust molecules. But the blue color which has shorter light waves is reflected back into the atmosphere. That is why the sky looks blue. The same principle applies with water in the sea or lake that looks blue.
