प्रश्न
In which of the three media, air, water or iron, does sound travel the fastest at a particular temperature?
उत्तर
The speed of sound depends on the nature of the medium. Sound travels the fastest in solids. Its speed decreases in liquids and it is the slowest in gases. Therefore, for a given temperature, sound travels fastest in iron.
