10 Hz
The period of an 8000 Hz sine wave is 0.125 milliseconds. (1/8000)
The period of a 15MHz sine wave is 1 / 15MHz, or 0.066667 us, or 66 2/3 ns.
Period = 1/78.6 seconds = 0.01272 seconds
The period of 1GHz is 1 ns. The waveform is irrelevant.
10 Hz
The frequency is the reciprocal of the period. In other words, divide 1 by the period. If the period is in seconds, the frequency is in hertz.
Period = 1 / frequency = 1/272 = 0.003676 second (rounded)
The period of an 8000 Hz sine wave is 0.125 milliseconds. (1/8000)
The period of a 15MHz sine wave is 1 / 15MHz, or 0.066667 us, or 66 2/3 ns.
The period is 1 millisecond.
Period = 1/78.6 seconds = 0.01272 seconds
30.6 degrees
The period of 1GHz is 1 ns. The waveform is irrelevant.
It is 1/810,000 = 0.00000123456790123456790... recurring.
The period of a wave can be calculated as the inverse of its frequency. In this case, the period would be 1/250 seconds, which is equal to 0.004 seconds.
The frequency of a wave is the reciprocal of its period, so if the period is 6 seconds, then the frequency is 1/6 Hz.
