Question
- A. The jumper reflects red wavelengths towards the eye and absorbs many other wavelengths.
- B. The jumper transmits red wavelengths through the material so the eye sees red light from behind it.
- C. The jumper produces ultrasound echoes that the eye detects as red.
- D. The jumper refracts every colour by the same amount, so only red remains visible.
Answer
The correct answer is: The jumper reflects red wavelengths towards the eye and absorbs many other wavelengths.
Explanation
The jumper reflects red wavelengths towards the eye and absorbs many other wavelengths. is correct. An opaque object is seen by reflected light, not transmitted light. The red appearance is evidence that red wavelengths reach the eye while other wavelengths are mostly absorbed by the fabric.
