Umaga = 3π rad/s
k(x) = k(1)=8π
The wavelength:
Lamda =2π/k
= 2π/8π = 0.25m
The speed of the associated wave
V= Umaga/k
= 3π/8π = 0.75m/s.
The oscillations of two points x1 and x2 at x = 0 and x = 1 m respectively are modelled as
follows:
y1 = 0.2 sin 3pt
and y2 = 0.2 sin (3pt +
8
p
)
Calculate the wavelength and speed of the associated wave.
