355118 A surface of area \(S\) is placed perpendicular to the direction of travel of a plane wave. The energy per unit time intercepted by the surface is \(E\) when the amplitude of the wave is \(A\). The area of the surface is reduced to \(1/2\;S\) and the amplitude of the wave is increased to \(2\;A\). What is the energy per unit time intercepted by this smaller surface?
355121 The \((x, y)\) coordinates of the corners of a squareplate are \(\left( {0,0} \right)\), \(\left( {L,0} \right)\), \(\left( {L,L} \right)\), and \(\left( {0,L} \right)\). The edges of the plates are clamped and transverse standing waves are set - up in it. If \(u\left( {x,y} \right)\) denotes the displacement of the plate at the point \(\left( {x,y} \right)\) at some instant of time, the possible expression for \(u\) is \(\left( {u\,{\text{ = }}\,{\text{positive}}\,{\text{constant}}} \right)\)
