Sine and Cosine Wave Projection Moving Graphics Regular Change Physics Simple Harmonic Vibration Projection Demonstrator

Features

• The regular changes of sine or cosine formed by projecting the light on the light screen through the vibrating shrapnel reflector.
• This instrument consists of a metal frame source, vibrating shrapnel, incident mirror light screen, speed-regulating motor, polygonal reflector, etc.
• , the magnitude of the external force of simple harmonic motion is proportional to the displacement. The motion parameters of an object change with time according to the law of sine or cosine.
• This instrument should be handled with care during experiments. After use, store the instrument in the order it is opened and store it in a dry place.
