Answer to Problem 10RAT

The correct option for the option for the statement, “the redness of a sunset is due to light that” is option (b).

Explanation of Solution

The object's color is due to the reason that objects reflect the color in which it appears and absorbs the rest of the colors. There are various colors in nature that exist due to the variation in the wavelength. The red color scatters the least compared to other colors because it has the longest wavelength. A person is able to see the sky due to the light from the Sun. The atmosphere of the Earth scatters the blue and violet color the most.

During a sunset, the Sun is on the horizon, and light from the Sun requires to travel a longer distance. In this time period, the dominant color reaching the sky red, and the rest of the colors get scattered. Therefore, the red color survives scattering in the sky, and redness can be seen in the sky.

Conclusion:

Therefore, the correct option for the option for the statement, “the redness of a sunset is due to light that” is option (b).
