More Information
Summary:The invention discloses a Pasco single/double-slit optical experiment demonstration device, which comprises a computer and a sliding rail, a disc with slits and a laser generator are slidably connected to the sliding rail, an iron plate is arranged on one side, far away from the laser generator, of the disc, a guide groove is formed in the iron plate, a pin shaft is slidably arranged in the guide groove, and the pin shaft is connected with the sliding rail through a bolt. A sliding block is fixedly arranged on the pin shaft, the sliding block slides back and forth through a crank connecting rod mechanism, a fluorescent screen is fixedly arranged at the upper end of the sliding block, a crank and a connecting rod are driven by a motor to rotate, and rotation is changed into slow left-right stable movement of the pin shaft driven by the connecting rod; therefore, bright fringes of a diffraction or interference pattern can sequentially pass through a lighting opening of the light sensor, errors caused by factors
