Question

Sky appears blue at noon because:

• A. All particles in the sky are blue.
• B. Blue is scattered more than other colors because it travels as shorter, smaller waves.
• C. There is no explanation for this phenomena.
• D. Due to atmospheric refraction.

Answer 1

The correct option is B Blue is scattered more than other colors because it travels as shorter, smaller waves.

When Sunlight enters into earth's atmosphere, it is scattered in all directions by all the gases and particles in the air. Blue is scattered more than other colors because it travels as shorter, smaller waves which interact with the atmospheric particles and gases the most. That’s why we see a blue sky most of the time.
