Question

Identify the true statement.
Choose one:

A. Aerosols scatter only light waves with short wavelengths.
B. The sky looks blue because atmospheric gas molecules are scattering blue light.
C. Clouds are white because they absorb the entire spectrum of visible-light colors.
D. Blue light has a longer wavelength than red light.

Answer 1

Answer:

B. The sky looks blue because atmospheric gas molecules are scattering blue light.

Explanation:

• As the blue light is scattered in all directions due to the presence of the tiny molecules of air in earth atmosphere and due to its shorter waves length this light gets scattered more to far distances and thus we see most of the time blue light in the sky.
