Sound waves move in air at a speed of 340 m/s. A trumpet plays a note: the sound wave made by the trumpet has a wavelength of 0.5 m. The sound wave then travels into a concrete wall. a. What is the frequency of the wave in air? Show your work. b. The same wave has a wavelength of 10 meters in the concrete wall. What is the speed of sound in the concrete? Show your work.
