Waves, Sound and Light: Sound Waves


We have 23 ready-to-use problem sets on the topic of Sound Waves. These problem sets focus on the application of wave principles to analyze wave phenomenon such as echoes, the Doppler shift, sound intensity, the decibel scale, and musical instruments that rely on resonating strings and air columns.
