 Admin P: 21,865 Think about what the time delay, 1.56 ms means in terms of the period, i.e. what fraction of the period, and how it relates to the wave length. If one has a signal - A sin$\omega$t, and another signal of the same form but at a delayed time of td, one could write the delayed signal as A sin$\omega$(t - td).
