The sound wave travelled the fastest through Helium.
- The speed of sound is greatest through Helium followed my metal pole and the slowest is through glass of water.
- The speed of sound through the metal pole is almost 17 times greater than speed of sound and that through class of water is four times greater than that through air.
- But Helium is an exception, even after low density speed of sound is fastest in it.
