Q. Sound travels at the fastest speed in

  • (A) steel
  • (B) water
  • (C) air
  • (D) vacuum
📝 Notes
✅ Correct Answer: (A) steel
Explanation: Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air.
