So, no impulsive force comes on you, so you do not feel kind of excitation, so there if frequency of encounter becomes so called the period is 0. So, this is called encounter frequency which is very critical, because the period at which the ship experiences excitation is not the period of the absolute wave, but because the the, but something else
as observed by moving ship. So, we have to first come with a formula for what is that that period.
If the aim of the ship are moving are about the same speed then that he know encounter the curve.
Exactly there is now you know that this is
