The period of an 8000 Hz sine wave is 0.125 milliseconds. (1/8000)
10 Hz
Frequency = 1 / period = 1 / 0.807 = 1.2392 Hz (rounded)

Period = 1 / frequency = 1/272 = 0.003676 second (rounded)
Frequency = 1 / period = 1 / 0.807 = 1.2392 Hz (rounded)
The signal that changes at a higher rate occupies greater bandwidth.
Wavelength = (speed)/(frequency)For a 10,000 Hz wave:,Wavelength = (speed)/(10,000) metersThat's (speed) x 100,000 nanometers.,For a 20,000 Hz wave:,Having doubled the frequency, the wavelength has now been reduced by half.So wavelength is now (speed) x 50,000 nanometers.,Note: It's often nice to be able to work with sine waves, but when you're only talking about frequency and wavelength, the wave-shape doesn't matter.

Hertz and Frequency are the same thing = cycles-per-second. When used for the vibration of something .. like an electromagnetic sine-wave . . . then if that sine-wave is vibrating with a frequency between 20 Hz and 20,000 Hz, the human ear can "hear" it. If an electromagnetic wave vibrated much faster .. around 10^^15 Hz, then you'd be able to SEE it.
