Volcanic eruptions rich in sulfur produce yellow sunsets.
   a. True
   b. False

Q. 2

When the atmosphere becomes loaded with particles, only the longest red wavelengths are able to penetrate the atmosphere, so we see a red Sun.
   a. True
   b. False

Q. 3

Haze can scatter light from the rising or setting Sun in a way that produces bright light beams, called anticrepuscular rays, radiating across the sky.
   a. True
   b. False

Q. 4

A whitish halo around the Sun, or a bright sheen visible in a nearby layer of thin clouds, is often the result of Mie scattering.
   a. True
   b. False

Q. 5

As sunlight enters the atmosphere, the shorter visible wavelengths of violet, blue, and green are scattered more by atmospheric gases than are the longer wavelengths of yellow, orange, and especially red, which is why the sky appears blue.
   a. True
   b. False

Q. 6

Each air molecule of oxygen and nitrogen is a selective scatterer in that each scatters longer waves of visible light much more effectively than shorter waves.
   a. True
   b. False

Q. 7

A star much hotter than our Sun radiates more energy at shorter wavelengths and thus appears redder.
   a. True
   b. False

Q. 8

The Sun radiates almost half of its energy as visible light.
   a. True
   b. False
