Question

what's the velocity of a sound wave traveling through Air at a temperature of 20 degrees Celsius

Answer 1

The velocity of a sound wave as a function of the temperature of the air is given by the equation

$V=331+\text{0}.6\cdot T$

Where T is the temperature in degrees celsius.

Using this equation, calculate the velocity of a sound wave at 20 degrees Celsius:

$V=331+0.6\cdot20=331+12=343$

Answer: the velocity is 343 m/s
