DEVICE TO DEMONSTRATE LIGHT DIFFRACTION OCCURRENCE ON OPTICAL GRATING

摘要

Stimulator consists of basic plate (1) and two parallel arms (2 and 3) swively fixed on basic plate (1). Arms (2 and 3) are on opposite side to rotary axis bounded with partition wall (4). On basic board (1) is schematically drawn the plane harmonic wave (5) and optic grid (6). On arms (2 and 3) are drawn sine curves, whose period answers the wave length of wave, which difraction is demonstrated.
