Passage-3A plane pressure pulse, triangular in shape, approaches a rigid wall along normal at a speed of400m/s. At time t = 0, situation is shown in the figure. The peak pressure is 100Pa. The pulse getsreflected by the wall and pressure near the wall gets doubled. Height of the wall is 2 m and width isalso 2m. A detector on the wall records a minimum excess pressure of 16 Pascal.
