In which medium speed of sound is the highest- Solid, Liquid or Gas? How?
The speed of sound is highest in solid.
The speed of sound depends on the density of the medium through which it is travelling. The higher the density of the medium, the faster is the propagation of sound. Since density of solids is higher than that of liquids and gasees, so sound travels faster in solids. Also, the molecules in the solid medium are closely packed together than in liquids or gases, allowing sound waves to travel more quickly through it.
