Answer:
Explanation:
First of all, we can find the speed of the sound wave, which is given by:
where
f = 645 Hz is the frequency
is the wavelength
Substituting,
Now we can find the temperature of the air by using the following relationship:
where T is the temperature in Celsius degrees. Since we know v = 322.5 m/s, we can re-arrange the formula to find the temperature:
Answer:
