The displacement of a sinusoidal wave at time t (s) and position x (m) is expressed by y(t) = 0.5sin[2π(t/2.0+x/0.40)]. What is the wavelength of the wave in m? Note that all units are SI units.
k = 2 pi / 0.4
2 pi /L = 2 pi / 0.4
L = 0.4 m

Comment before rate in case any doubt, will reply for sure.. goodluck
