![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. If 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?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F77ff0dc1-7282-4fa0-94cd-a91857c24dd6%2F062e3684-b085-4314-90b5-2d11b6100a0b%2F6eti8di_processed.jpeg&w=3840&q=75)
