Question
In which of the following mediums does the sound propagate at the highest speed?
- Air
- Water
- Iron block
- It moves at the same speed in all the above mediums
Hint:
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.
