1kHz
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.
To find the equation of a sine wave, you need to know the amplitude, period, and phase shift of the wave. The general form of a sine wave equation is y Asin(B(x - C)), where A is the amplitude, B is the frequency (related to the period), and C is the phase shift. By identifying these values from the given information or graph, you can write the equation of the sine wave.
10 Hz
The period of 1GHz is 1 ns. The waveform is irrelevant.

A sine wave is used for transmission - and not a square or triangular wave - because a sine wave is the most efficient waveform to use and also because it can be generated using normal copper windings in alternator rotors and stators without needing much, if any, "wave shape improvement" equipment. The deliberate production of either square or triangular waves would waste a huge amount of energy, both in the power generation plant and in the many transformers used in the power distribution network.

Period = 1 / frequency = 1/272 = 0.003676 second (rounded)
1 divided by 100,000,000.00 in sec
the length of time it takes to complete one cycle
The period is the reciprocal of the frequency, in this case, 1/250 second.
