Question

1. what color wavelengths of visible light does person b see?

a
a
visible spectrum
b
north pole
b
short
lon
a. blue & purple because the wavelengths are shorter
b. blue & purple because the wavelengths are longer
c. red & orange because the wavelengths are shorter
d. red & orange because the wavelengths are longer

1. why do different colors of light scatter differently within our atmosphere?

a. different levels of the atmosphere vary in temperature.
b. all colors scatter at the same location within our atmosphere.
c. different colors of light have different wavelengths.
d. some colors are absorbed by clouds.

1. temperatures are warmer when?

a. the days are longer and the nights are shorter.
b. the days are shorter and the nights are longer.
c. when both the days and nights are short.
d. when both the days and nights are long.

1. when it’s winter in michigan (in the northern

hemisphere), what season is it in australia (in the
southern hemisphere), and why?
a. summer, because the southern
hemisphere is tilted toward the sun.
b. winter, because the southern hemisphere
is tilted away from the sun.
c. fall, because the earth is closer to the sun
in the northern hemisphere.
d. spring, because the sun’s rays are the same in both hemispheres.

Explanation:

Question 4

Step1: Recall visible spectrum wavelengths

Visible light spectrum: shorter wavelengths (e.g., blue, purple) vs longer (e.g., red, orange). Sunset/sunrise light (for person B? Wait, the diagram: Person B's light path—wait, the question is about person B? Wait, the options: D is Red & orange because wavelengths are longer. At sunset, light travels through more atmosphere, shorter wavelengths (blue, purple) scatter more, leaving longer wavelengths (red, orange) to be seen. So person B (maybe at sunset) sees red/orange with longer wavelengths. So option D.

Step2: Analyze options

• A: Blue/purple, shorter—incorrect (sunset has longer wavelengths seen).
• B: Blue/purple, longer—wavelengths of blue/purple are short, so B's reasoning wrong.
• C: Red/orange, shorter—red/orange have longer wavelengths, so C wrong.
• D: Red/orange, longer—correct, as red/orange have longer wavelengths, and at sunset, these are left after short wavelengths scatter.

Step1: Recall Rayleigh scattering or light scattering principles

Light scattering in atmosphere depends on wavelength. Different colors (light) have different wavelengths (e.g., blue ~450nm, red ~650nm). Scattering (like Rayleigh) is inversely related to wavelength^4, so different wavelengths scatter differently.

Step2: Analyze options

• A: Temperature of atmosphere levels—scattering not about temp levels, but wavelength. Incorrect.
• B: All colors scatter same location—false, different wavelengths scatter at different altitudes/amounts.
• C: Different colors have different wavelengths—correct, as wavelength determines scattering (e.g., blue scatters more in upper atmosphere, red less).
• D: Some colors absorbed by clouds—scattering is about interaction with air molecules, not cloud absorption for this question. Incorrect.

Step1: Recall seasons and day/night length

Warmer temperatures occur when a region gets more solar radiation, which is when days are longer (more hours of sunlight) and nights shorter (less time without sun), so more energy absorbed.

Step2: Analyze options

• A: Days longer, nights shorter—more sunlight, warmer. Correct.
• B: Days shorter, nights longer—less sunlight, colder (winter). Incorrect.
• C: Both days and nights short—equinox? Not warmer. Incorrect.
• D: Both days and nights long—polar regions? Not warmer generally. Incorrect.

Answer:

D. Red & orange because the wavelengths are longer
