Approaching source Doppler frequency
In a second version of the same wave investigation, a source in a school sound lab moves toward a stationary observer at \(10\,\text{m s}^{-1}\). The emitted frequency is \(520\,\text{Hz}\), and sound speed is \(340\,\text{m s}^{-1}\). Calculate the observed frequency. Use the diagram first, then calculate the requested value. Enter the numerical result and choose the interpretation that matches the wave meaning.
