Question

In which of the following mediums does the sound propagate at the highest speed?

  1. Air
  2. Water
  3. Iron block
  4. It moves at the same speed in all the above mediums

hintHint:

The sound propagates at the highest speed in the iron block.

The correct answer is: Iron block


    • The sound is a mechanical wave that requires high a strong medium to travel.
    • The speed of sound will be more in the solid medium than in air.
    • The speed of a sound wave is faster in the iron block.
