The frequency of a sine wave is defined as:
a. the number of cycles per second
b. the maximum amplitude of the wave
c. the time for one cycle
d. the difference between the high frequency and the low frequency

a.the number of cycles per second

Explanation:

The frequency of a sine wave is defined as the number of cycles per second.

Frequency is the inverse of the time period. The frequency of a sine wave is given by 1/TimePeriod . It is generally expressed in units of Hertz(Hz) or sec^-1. Larger the time period, lower will be the frequency and vice versa. So for higher frequency waves we need to ensure that the time period is small.
