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)
0.02
4 Hz
Frequency = reciprocal of period = 1/P = 1/0.008 = 125 Hz.
10 Hz
The length of a Hz sine wave can be calculated using the formula: length = 1/frequency. For example, for a sine wave of 1 Hz, the length would be 1 second. This formula is derived from the relationship between frequency (number of cycles per second) and the period (duration of one cycle), where period = 1/frequency.
Period = 1 / frequency = 1/272 = 0.003676 second (rounded)
Frequency = 1 / period = 1 / 0.807 = 1.2392 Hz (rounded)
Period = 1/frequency = 1/60 = 16 and 2/3 milliseconds
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.
The signal that changes at a higher rate occupies greater bandwidth.
The period of a 4 Hz wave is 0.25 seconds. Period is the time it takes for one complete cycle of a wave to occur. In this case, for a 4 Hz wave, the wave completes one full cycle every 0.25 seconds.
The frequency of a wave is the reciprocal of its period. So, if the period of the wave is 5 seconds, the frequency would be 1/5 Hz, which is 0.2 Hz.
5 cycles.
.05 seconds
The period is the reciprocal of the frequency. If the frequency is in Hz, the period is in seconds.
