How to know why the sunset is red

When the sun begins to rise in the morning, the sky often appears red, especially if there is a cloud around it. During the day, when the sun is high, it looks yellow and the sky is blue. When the sun sets it becomes a strong red color and the sky pink. Does it really change color or does it just seem like they do it? If you look at the following article, how to know why the sunset is red, you will know the answer.

  • Pitcher of water
  • Cold water
  • Milk
  • Lantern
Steps to follow:

Why it happens. The earth is surrounded by an air layer filled with dust particles and water droplets. Dust and drops of water, like milk in a glass of water, disperse the blue part of the sunlight and make the sky look blue. When the sun is low in the sky, it looks red because its light has to go farther through the air and only the red part reaches your eyes.
