A car horn creates a 595 Hz tone at rest. Two cars pass on the street, each going 20 m/s; the first car honks. What frequency does the other car hear after they pass each other? (speed of sound = 343 m/s) (unit = Hz). PLEASE HELP

The frequency does the other car hear after they pass each other is 631.8 Hz.

Frequency heard by the second car

The frequency heard by the second car is calculated as follows;

f = f'(v/v - vs)

where;

  • f' is the original frequency
  • f is the later frequency heard
  • v is speed of sound
  • vs is source speed

f = 595(343/343 - 20)

f = 631.8 Hz

Thus, the frequency does the other car hear after they pass each other is 631.8 Hz.
