de Onda debe tener esta para que una persona perciba el sonido con una
frecuencia de 20 Hz?.



Answer :

GinnyAnswer

Final answer:

The frequency heard by a person depends on both the speed of sound and the observer's speed.


Explanation:

The frequency heard by a person driving towards a sound source is different due to the Doppler effect. To calculate this, we use the formula:

f' = f(v + vo)/(v +- vs)

Where:

  • f = given frequency of the sound source (800 Hz)
  • v = speed of sound in air (340 m/s)
  • vo = speed of the observer (15 m/s)
  • vs = speed of the source
