SUMMARY
The discussion focuses on calculating the temperature of air based on the frequency and wavelength of a sound wave. Given a frequency of 722 Hz and a wavelength of 0.54 m, the velocity of sound is calculated to be 389.88 m/s. The relationship between the velocity of sound and temperature is established using the formula V/Vo = √(T/To), where Vo is the velocity of sound at 0 degrees Celsius (327 m/s). This formula indicates that temperature must be measured on an absolute scale for accurate calculations.
