-- If the ocean waves lap the shore every 15 seconds then their frequency is 1/15 Hz.
-- If the waves come every 30 seconds then the frequency is 1/30 Hz.
-- If the waves come every minute (60 seconds) then their frequency is 1/60 Hz.

In general, the frequency of ocean waves, and any other waves, is
1/the number of seconds between consecutive waves10m x 0.05 /sec = 0.5 m/s 20 hz
A 100 Hz electromagnetic wave has length of about 1,862.82 miles.
if the cycle lasts 5 seconds, then the frequency is 0.2 Hz
5.0 hz
It depends on whether or not it is a half wave or full wave rectifier. For a single phase 60 Hz rectifier, a half wave rectifier will be 60 Hz while a full wave rectifier will be 120 Hz. A three phase full wave rectifier will be 360 Hz.
There should be two beat frequencies produced: 506 Hz and 6 Hz.
The period of an 8000 Hz sine wave is 0.125 milliseconds. (1/8000)
The frequency 55 Hz has a wavelength of about 6.23meters.
The speed is almost the same, for different frequencies.
.05 seconds
340 m/s
For 440 Hz: λ = about 423.37 miles.
