Chapter 4, Problem 45AP

A piano tuner uses a tuning fork that emits sound with a frequency of $\text{44}0{\text{ s}}^{-\text{1}}$ . Calculate the wavelength of the sound from this tuning fork and the time the sound takes to travel 10.0 m across a large room. Take the speed of sound in air to be ${\text{343 m s}}^{-\text{1}}$ .
