Frequency is a measurement of how often a recurring event such as a wave occurs in a measured amount of time. One completion of the repeating pattern is called a cycle. Only moving waves which vary their positions with respect to time possess frequency. Frequency is one way to define how fast a wave moves.
Part (a): The wave's amplitude, wavelength, and frequency can be determined from the equation of the wave: y(x,t) = (0.9 cm) sin[(1.2 m -1)x - (5.0 s -1)t]. The amplitude is whatever is multiplying the sine. A = 0.9 cm. The wavenumber k is whatever is multiplying the x: k = 1.2 m -1.
