Ripple tank single slit diffraction with varying slit and wavelength. 3B50.12 ripple tank diffraction S-144 Use the ripple tank to show radiation patterns from different baffle, pipe, and horn configurations. Two point sources show interference. A plane wave through a slit shows diffraction. A ripple tank with two point sources in phase.
Waves produced by audio oscillators drive beads attached to earphone diaphragms.
Sm-5 Interference from a plane wave passing through a double slit in the ripple tank. Ripple tank double slit interference with varying wavelength and slit separation. 3B50.30 ripple tank - film loops PIRA 500 3B50.30 ripple tank film loop 3B50.30 3B50.40 Moire pattern transparencies PIRA 200 A double slit representation of Moire patterns from two sheets of semicircular ruled transparencies. 3B50.40 Morie pattern transparencies 3B50.40 Transparencies with identical circular patterns are placed on top of each other with a slight offset. 3B50.40 Moire pattern 35-2.1 Moire patterns from two sheets of semicircular ruled transparencies form a double slit representation.
