Problem

A wave travelling along a string is described by

y(x, t) = 0.005 \sin (80.0 x - 3.0 t),

in which the numerical constants are in SI units (

0.005

80.0

rad

m^{-1}

and

3.0

rad

s^{-1}

). Calculate (a) the amplitude. (b) the wavelength (c) the period and frequency of the wave. d. Also, calculate the displacement

y

of the wave at a distance

x = 30.0

cm and time

t = 20
