Velocidade dos sons

Not surprisingly, the speed of sound depends on the medium of travel of the sound waves. Usually, we will talk about sound in dry air, so here we are only concerned about the speed of sound in dry air! For this reason, we will just mention that the it is dependent on only one more variable $-$ namely, the temperature of the air (the medium). The formula is the following.

If $T$ is the temperature of the air in degrees Celsius, then the speed of sound, in m/s, of sound in the air is $$v = 331 + 0.6 \cdot T.$$ For example, at $T = 20^\circ \, \text{C}$(very close to room temperature), the speed of sound is $v = 343 \, \text{m/s}$.

Speed of sound is greater in Glass as compared to Iron at 20°C.
