Crumbles · Answer 1

612 Hz.

Step-by-step explanation:

The frequency of the sound will be proportionally higher when coming towards you. The increase is related to the speed of the train.

So the frequency will be:

580 + (580 / 343) * 18.8

= 612 Hz.

This is called the Doppler effect.

612 hz

Step-by-step explanation:

580 + (580 / 343) * 18.8

= 612 Hz.
