Answer options

  1. 100 Å
  2. 10 Å
  3. 1000 Å
  4. 0.1 Å

Correct answer and explanation

Correct answer: 10 Å

Explanation: ✅ Correct Answer: B) 10 Å 📚 Explanation: A nanometer (10-9 meters) and an Ångström (10-10 meters) are incredibly small units used to measure atomic dimensions and wavelengths of light. Because one nanometer is exactly ten times larger than one Ångström, 1 nm is strictly equivalent to 10 Å. You might occasionally see older, unverified sources mistakenly quote 100 Å, but mathematically, it is exactly 10 Å.
