Question

Suppose you were bungee jumping from a bridge while blowing a hand-held air horn. How would someone remaining on the bridge hear the pitch of the air horn as time increased?

Answer 1

Pitch would decrease

Step-by-step explanation:

According to Doppler's effect, the apparent frequency (pitch) of a sound changes if there is relative motion between the source and the listener.

As the distance increases between the source and the listener, the apparent frequency heard by the listener would be lower than the source frequency.

So, as the bungee jumper would go up in the air, the listener standing on the bridge would hear decreasing pitch.

Answer 2

The pitch will progressively lower

Step-by-step explanation:

If i were bungee jumping from a bridge while blowing a hand-held air horn and someone who remains on the bridge will hear a decreased pitch or frequency as the source is moving away from the stationary listener as per the Dooplers effect. Hence, the pitch will progressively lower as the source is moving away from the observer.
