- Sine waves are used to model many periodic and vibrational patterns in nature.

- The equation y = A sin (kT) represents a set of ordered pairs of the form (T,y).

- When graphed on a horizontal T-axis and vertical y-axis, the curve represented by y = A sin (kT)

is a Sine wave having vertical amplitude = |A| and horizontal wavelength = |2(Pi)/(k)|.

- In a vibrating string example, |A| is the maximum deflection of the string from rest position.

Wavelength refers to how long it takes for a pattern to repeat itself. Eg. a crest + a trough .

As 'k' gets larger in size, the wavelength gets shorter. Also Pi = 3.14159 approximately.
