Why can gamma rays pass through materials that stop visible light completely?
ALower frequency radiation penetrates matter more readily
BGamma rays travel slower, so they slip through gaps
CGamma rays carry no energy, so nothing can absorb them
DHigher frequency radiation penetrates matter more readily
Answer & Solution
Correct answer: D. Higher frequency radiation penetrates matter more readily
1. Higher frequency radiation penetrates matter more readily than lower frequency radiation.
2. Gamma rays sit at the very high frequency end of the spectrum, well above visible light.
3. Their high frequency is exactly what lets them pass through material that stops visible light.
4. Gamma rays actually carry more energy than visible light, not none, so the claim about zero energy is false.
