Abstract

Laser pointers enable the instructor to make the old demonstrations more attractive and more vivid. Examples are offered for demonstrations of optical properties of heterogeneous systems (suspension, emulsion, colloid, smoke, fog etc.), where the light scattering on the dispersed particles reveals the non-homogeneity of the system. Two more remarkable demonstrations are added (using a green laser pointer) covering for fluorescence and photochromism phenomena.
