Abstract

The transparent plastics bar is of uniform transverse section and the whistle notch is defined by an outer transverse plane perpendicular to the axis of the bar and an inner oblique plane constituting in air a surface of total reflection for any incident light ray. The end of the bar beyond the notch is pref. etched or brightly coloured, e.g. by colouring of the plastics itself. The section of the bar may be round or oblong.
