A train blows its whistle to warn traffic of its approach. The sound waves are moving at a speed of 331 m/s. The frequency of the waves is 15 Hz. What is the wavelength?

1 answer

Wavelength = V * 1/F = V/F = 331/15 = 22.07 m.

Note: 15 Hz means 15 cycles/second.
The wall sockets in our homes are 60 cycles/second(cps).

9
cps).
