Question

when sunlight strikes air particles, the light is scattered in all directions. this is called diffraction. air molecules scatter some colors of light better than others. blue light is scattered the most, and red light is scattered the least. in fact, blue light is scattered at least ten times more than red light. since the blue rays of light are scattered the most, they reach our eyes from all directions, and we see more blue than any other color. what is the main idea of this passage? air molecules scatter light in all directions. diffraction causes the sky to look blue. sunlight has more blue than any other color. air molecules don’t diffract red light very well.

Explanation:

The passage explains that when sunlight hits air particles, light is scattered (diffraction). Blue light is scattered more than other colors like red, making the sky appear blue as more blue - light reaches our eyes from all directions.

Answer:

B. Diffraction causes the sky to look blue.
