We can define the speed of sound as the speed at which sound waves propagate through different materials.
Speed of sound varies in every medium;for instance, the speed of sound through air is different from the speed of sound through a brick wall.
Formula to calculate the speed of sound.
Calculate the speed of a sound wave whose 17.15 meters and has a frequency of 20 Hertz.
Therefore, the speed of sound is 343 m/s.
Below is a chart of speed of sound in different materials.
|Material||Speed of Sound|
|Air at 40 °C||355 m/s|
|Air at 20 °C||343 m/s|
Therefore, from the chart we can see that the speed of the sound we were calculating is through air at 20 °C .
