A source S and a detector D are placed at a distance dapart.A big cardboard is placed at a distance V2d from
the source and the detector as shown in figure (16-E2).
The source emits a wave of wavelength =d/2 which is
received by the detector after reflection from thecardboard. It is found to be in phase with the directwave received from the source. By what minimumdistance should the cardboard be shifted away so thatthe reflected wave becomes out of phase with the directwave?
