Doppler Effect A car is travelling towards you at 16 m.s -1 sounding its hooter with a frequency of 320hz the. The velocity of sound is 330m.s-1 . what is the frequency of the sound that you will hear ?
Fo = (Vs+Vo)/(Vs-Vc) * Fc.
Fo = (330+0)/(330-16) * 320 =
To calculate the frequency of the sound that you will hear, we can use the formula for the Doppler Effect:
f' = f (v + vd) / (v + vs)
Where:
f' is the observed frequency
f is the actual frequency
v is the velocity of sound
vd is the velocity of the detector (in this case, you)
vs is the velocity of the source (in this case, the car)
In this case, the actual frequency (f) is 320 Hz, the velocity of sound (v) is 330 m/s, and the velocity of the car (vs) is 16 m/s. Since the car is traveling towards you, the velocity of the detector (vd) is 0 m/s.
Plugging these values into the formula:
f' = 320 Hz * (330 m/s + 0 m/s) / (330 m/s + 16 m/s)
Simplifying the equation further:
f' = 320 Hz * 330 m/s / 346 m/s
Calculating:
f' = 306.358 Hz
Therefore, the frequency of the sound that you will hear is approximately 306.358 Hz.
