Question

What colour seals would you attach to the trolley on a turnaround?

A) Red
B) Blue
C) Green
D) Yellow

Answer 1

Correct statements regarding the appearance of the colour wheel are: d.A, the blue section appears blue by reflecting blue light and absorbing red and green, and d.B, the yellow section appears yellow by reflecting red and green light and absorbing blue.

Step-by-step explanation:

The colour that objects appear depends on the colours of light they absorb and reflect. Light that is absorbed by an object is not seen, while the light that is reflected is the colour the object appears to us. When it comes to colour wheels and the appearance of colours:

• A. If the yellow section of the wheel absorbs blue light and reflects red and green, it will appear yellow.
• B. If the blue section of the wheel absorbs red and green light and reflects blue, it will appear blue.

The factual statement that correctly describes the appearance of the sections of the colour wheel would be:

• Option d.A, where the blue section of the wheel will look blue because it will reflect blue light and absorb red and green.
• Option d.B, where the yellow section of the wheel will look yellow because it will reflect red and green light and absorb blue.

Answer 2

The question is likely about the absorption and reflection of light on a color wheel in physics. While the context of the color seals on a trolley in turnaround is unclear, it can be affirmed that the blue section of the wheel will look yellow if it reflects red and green light and absorbs blue (Option B). Other options presented do not accurately describe the color phenomena.

Step-by-step explanation:

The question appears to be in reference to a scenario involving the perception of colors on a color wheel, possibly related to a physics experiment or demonstration regarding the reflection and absorption of light. The color seals associated with a turnaround don't relate directly to any standard physics notation, therefore the context seems to be missing or the question might be incomplete. Nevertheless, assuming the question is about how colors on a wheel appear when certain colors of light are reflected or absorbed:

• Option A: Incorrect. The yellow section will reflect both red and green light, making it appear yellow, not blue.
• Option B: Correct. The blue section will look yellow because it will reflect red and green light and absorb blue.
• Option C: Incorrect. The yellow section does not absorb blue light only to reflect red and green.
• Option D: Incorrect. Both statements are false based on how colors are perceived due to the absorption and reflection of light.
