A motorcycle and a police car are moving toward one another. The police car emits sound with a frequency of 523 Hz and has a speed of 32.6 m/s. The motorcycle has a speed of 13.6 m/s. Part A What frequency does the motorcyclist hear

The frequency the motorcyclist hears is 601.60 Hz

Explanation:

The Doppler effect is a physical phenomenon where an apparent change in wave frequency is presented by a sound source with respect to its observer.

The following expression is considered the general case of the Doppler effect:

Where:

f ’, f: Frequency perceived by the receiver and frequency emitted by the emitter respectively. Its unit of measurement in the International System (S.I.) is hertz (Hz), which is the inverse unit of the second (1 Hz = 1 s-1)

v: propagation speed of the wave in the medium. It is constant and depends on the characteristics of the medium. In this case, the speed of sound in air is considered to be 34o m / s

vR, vE: Receiver and emitter speed respectively. Your unit of measure in the S.I. is the m / s

±, ∓:

The + sign is used:

The sign - is used:

In this case:

Replacing:

Solving:

f' = 601.60 Hz

The frequency the motorcyclist hears is 601.60 Hz

what is the actual question though?
