An unknown source plays a pitch of middle c (262 hz). how fast would the sound wave from this source have to travel to raise
the pitch to c sharp (271 hz)? use 343 m/s as the speed of sound.
a. 2.8 m/s
c. 11.4 m/s
b. 15.6 m/s
d. 8.2 m/s

The sound travels at

Option: c

Explanation:

Unknown source plays of middle C (fs) = 262 Hz

The sound wave from this source have to travel to raise the pitch to C sharp is (fd) = 272 Hz

Substitute the given values in the formula,

Therefore, The sound travels at
