Question

Sunsets are red because

a.larger particles in the air preferentially scatter light of lower frequencies.

b.smaller particles in the air preferentially scatter light of lower frequencies.

c.air molecules preferentially scatter light of higher frequencies, leaving behind light of lower frequencies.

d.orange-red light is reflected more strongly by cloud and other larger particles in the air.

e.oxygen in the air has a slight orange-red tinge. When light passes through large amounts of air, the oxygen in air filters out light of other colors, leaving behind orange-red light.

Answer 1

Sunset is red because smaller particles in the air preferentially scatter light of lower frequencies.

During sunset smaller particles in the air(aerosols) scatter lower frequency/larger wavelength light towards us, thereby giving the sunset a reddish color.

Option B) is the right answer
