2. the sky is blue because:

group of answer choices

air transmits blue light but absorbs all other colors.

the average temperature of the atmosphere is such that the air molecules emit mostly blue light.

air molecules scatter blue light more efficiently than other colors.

air has the color of the light that is reflected by the earth's surface, which is two-thirds blue ocean.

Air molecules scatter blue light more efficiently than other colors.

Explanation:

The sunlight has many colors and each of them has a different wavelenght. The color blue has shorter wavelengths and higher frequencies than the other colors. So, as sunlight goes through the air, the blue part causes charged particles to oscillate faster than the red part does and it is scattered more efficiently than the other colors and that's the reason for the sky to be blue.
