Why does an apple appear red in color?

• A. It reflects red wavelengths of light and absorbs other wavelengths.
• B. It absorbs red wavelengths of light and reflects green wavelengths.
• C. It contains chlorophyll, which reflects blue light.
• D. It emits red light due to cellular respiration.

Answer: (A)

Verified step by step guidance

1. Understand the concept of light reflection and absorption: Objects appear a certain color because they reflect specific wavelengths of light while absorbing others. The color we perceive is the wavelength of light that is reflected.
2. Analyze the options provided: The first option states that the apple reflects red wavelengths of light and absorbs other wavelengths. This aligns with the principle of light reflection and absorption.
3. Eliminate incorrect options: The second option suggests the apple absorbs red wavelengths and reflects green wavelengths, which would make the apple appear green, not red. The third option mentions chlorophyll, which is not relevant to the color of an apple. The fourth option incorrectly attributes the color to cellular respiration, which does not emit visible light.
4. Focus on the correct explanation: The apple appears red because it reflects red wavelengths of light, which are detected by our eyes, while absorbing other wavelengths.
5. Conclude the reasoning: The correct answer is based on the physical properties of light and the apple's surface, which selectively reflects red wavelengths.
