Question

1 person a is representing a person at sunset. why would person a see the colors red and orange in the sky during a sunset?
sunlight traveling to person a is traveling through more atmosphere, so longer wavelengths of color are reaching person a.
sunlight traveling to person a is traveling through less atmosphere, so longer wavelengths of color are reaching person a
sunlight traveling to person a is traveling through more atmosphere, so shorter wavelengths of color are reaching person a
sunlight traveling to person a is traveling through less atmosphere, so shorter wavelengths of color are reaching person a.

Explanation:

To determine the correct answer, we analyze the phenomenon of sunset colors. During sunset, sunlight travels through a thicker (more) layer of the atmosphere to reach an observer (person A). Shorter - wavelength light (like blue and violet) is scattered more by the atmosphere, while longer - wavelength light (like red and orange) is scattered less and can reach the observer.

• Option 1: "Sunlight traveling to person A is traveling through more atmosphere, so longer wavelengths of color are reaching person A." This matches the explanation.
• Option 2: Claims sunlight travels through less atmosphere, which is incorrect as sunset light travels through more atmosphere.
• Option 3: Says shorter wavelengths reach person A, but shorter wavelengths are scattered more and don't reach, so this is incorrect.
• Option 4: Incorrectly states less atmosphere and shorter wavelengths reaching, which goes against the physics of light scattering in the atmosphere.

Answer:

A. Sunlight traveling to person A is traveling through more atmosphere, so longer wavelengths of color are reaching person A.
