Question

your friend says that he heard about some rocks that would glow when they were put under a certain kind of light. can light cause rocks to glow? no. light is not a physical thing, so it cannot change physical things like rocks. no. light can only change things by warming them up, so it cannot cause the rocks to glow. yes. light can pull energy out of the rocks, causing them to glow. yes. rocks can take in energy from the light, causing them to glow.

Explanation:

To determine the correct answer, we analyze each option:

• First option: Light is a physical entity (electromagnetic radiation), so this is incorrect.
• Second option: Light can cause effects other than just heating, like exciting electrons in materials to make them glow (fluorescence/phosphorescence), so this is wrong.
• Third option: Light doesn't "pull energy" from rocks; instead, rocks absorb light energy. This is incorrect.
• Fourth option: Some rocks (like fluorescent minerals) absorb energy from light (e.g., UV light) and then emit it as visible light, causing them to glow. This matches the scientific concept of how light can make rocks glow.

Answer:

D. Yes. Rocks can take in energy from the light, causing them to glow.
