The period of the sine curve is the length of one cycle of the curve. The natural period of the sine curve is 2Ï. So, a coefficient of b=1 is equivalent to a period of 2Ï. To get the period of the sine curve for any coefficient b, just divide 2Ï by the coefficient b to get the new period of the curve.
The time period of oscillation of a wave is defined as the time taken by any element of the string to complete one such oscillation. For a sine wave represented by the equation y (0, t) = -a sin(Ït), the time period is given mathematically as T = 2Ï/Ï. Frequency. The frequency of a sinusoidal wave can be defined as the number of complete oscillations made by any element of the wave per unit time. For a sinusoidal wave represented by the equation y (0,t) = -a, frequency of the wave is given by, Its unit is Hertz abbreviated as Hz. One Hertz is equal to one complete oscillation taking place per second.
