Answer:

here is your answer

Explanation:

Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

and.....

Thus, as sunlight of all colors passes through air, the blue part causes charged particles to oscillate faster than does the red part. ...
