If the, if I put a ship here, let me put a ship, let me draw another diagram sorry about the asymmetry of the diagram but what we will get? We will get a set of divergent waves like this, wing further away and excuse me a set of transverse waves. Now, as we have explained if it was created due to the fore part, if the fore part could be repainted by pressure point, then these wave should be created, and we have said that the transverse waves reduce in height as it goes forward, so as it goes sorry as the waves are further aft from the ship the height reduces.
