Question

8.
the barn above looks red because certain rays of light are absorbed by the barn and other rays of light are reflected by the barn.
what must be true about the original sunlight before it hits the barn?
○ the original sunlight cannot reflect off of objects.
○ the original sunlight is a mixture of colors.
○ the original sunlight contains only red rays.
○ the original sunlight contains mostly green rays.

Explanation:

To determine the correct answer, we analyze the concept of light absorption and reflection. For an object to appear red, it reflects red light and absorbs other colors. This implies the original sunlight must have multiple colors (a mixture) so that the barn can absorb non - red colors and reflect red.

• The first option is wrong because sunlight does reflect off objects (like the barn reflects red).
• The third option is wrong as if sunlight had only red rays, there would be no other colors to absorb, and the concept of absorption - reflection for color perception wouldn't work this way.
• The fourth option is wrong because the barn is red (reflects red) and green is absorbed (since the grass is green, it reflects green), so sunlight can't have mostly green rays. So the correct reasoning leads us to the option that the original sunlight is a mixture of colors.

Answer:

B. The original sunlight is a mixture of colors.
