1. Sounds waves are disturbances in air molecules that move at 343 + m/s. Pitch is a measure of a sounds frequency. A middle C note in music has a frequency (pitch) of 261.6 Hz. a. you are listening to a middle C, how many pulses (wave crests) of sound hit you in one minute (1 minute is exactly 60 seconds)? b. How far apart is each wave crest (wavelength) in a middle C note? c. If that note was sung louder, would either the wavelength or frequency change?
