Correct Option: D
Here's the breakdown:
- The Key Concept: The color of an object is determined by the wavelengths of light it reflects. Objects absorb most wavelengths and reflect specific ones.
- Red Light and a Red Shirt: A red shirt reflects red light. When viewed under red light, the shirt still reflects red light, making it appear red. However, under white light, the shirt absorbs all other colors except red.
- Why the Answer is D: The red shirt under red light absorbs other colors and reflects red.
