Answer:
310 Hz
Step-by-step explanation:
This is a spanish language mathematical question.
We translate this to english:
An observer approaches a static speaker at 15 meters per second. The speaker is emitting a sound with a frequency of 297 Hz. What is the frequency perceived by the observer?
<u>Solution:</u>
<u />
This can be solved using doppler effect formula. Which is:
Where
f is the observed frequency (297 Hz)
c is the speed of sound (343 m/s)
is the velocity of source (given as 15)
is what we want to find
Now, substituting, we solve:
Rounding,
<u>We can say the perceived frequency would be around 310 Hz</u>
