In which of the three media, air, water or iron, does sound travel the fastest at a particular temperature?

Answer 1

The speed of sound depends on the nature of material or medium through which it travels.

At room temperature a speed of sound in air is 344 m/s, speed of sound in water is 1500 m/s & the speed of sound in iron is 5130 m/s.

Hence, sound Travels slowest in gases faster in liquids and fastest in solids.

Therefore sound Travels fastest in iron..
