6. A person rings a bell and another person hears the sound. Draw a diagram (in your composition book) of how this sound is created, transmitted, and received by a human7. What is a waveform-the shape of a wave, a graph obtained by plotting the instantaneous values of a periodic quantity against the time.
8. Is sound two dimensional or three dimensional?-Three dimensional
9. How do variations in sound pressure correlate to a waveform diagram?-the more sound pressure the higher the wave and vice versa
