A vibration-testing system produces a sound wave that travels through a resin layer and then enters a ceramic layer. The source completes 900 oscillations in 0.060 s. The speed of sound is 1500 m/s in the resin and 6000 m/s in the ceramic.
Calculate the increase in wavelength when the sound wave passes from the resin into the ceramic.
