a wave travelling along a string is described by y=0.005sin(80x-3t) in which the constants are in SI unit. calculate the amplitude , wavelength , time period and freequency of the wave.

The given equation is y = 0.005 sin (80x - 3t)                  (1)
The general solution of a traveling harmonic wave is

Comparing the above equation(i) with the general solution,
Amplitude, a = 0.005m
