Question

A plane harmonic wave propagates along x axis in
positive direction. Given amplitude is 1.0m, period is
2.0s, wave length is 2.0m. At t=0, the particle at I
origin of coordinate located at the equilibrium
position moves positively alone axis Ov. Find:
(1) wave function.
(2) At t=1.0s, the distribution of displacement of all
the particles, and draw the graph at the time.
(3) The wave function of particles at x=0.5m, and
draw the relation curve between the displacement of
the particle and time.
( The wave function:
= A cos
T 20
) ])​
