Question

Higher the density of the medium _________ is the speed of the sound.

Answer 1

Speed of the sound:

1. Sound energy travels at different speeds in different mediums due to the difference in density of molecules.
2. The more dense a medium the more speed the sound travels through it.
3. For example the speed of sound in solid (steel) is 5000 m/s whereas in air medium (Gas) is 340 m/s.

Hence higher the density of the medium the faster is the speed of the sound.
