Problem

Consider a wave propagating in the negative

x

-direction whose frequency is 100 Hz. At

t = 5

s, the displacement associated with the wave is given by

y = 0.5 \cos (0.1 x)

where

x

and

y

are measured in centimetres and

t

in seconds. Obtain the displacement (as a function of

x

) at

t = 10

s. What is the wavelength and velocity associated with the wave?
