Double-Slit Experiment Single Slit Double Slits Combination Trellis Design Optics Elements Interference Diffraction Grating Sheet Optical Physical Experiment Kit$$Optical

Optics Elements for Interference Diffraction Optical Physical Experiment. Suitable for elementary and junior high school students, who are prepared for physics by understanding the interference and diffraction of light in advance. This kit is used in class to illustrate the phenomenon of light interference and stimulate children's curiosity. This film is made of PET material, please do not use high power laser to avoid damage to the film. Properly increasing the distance between the observation plate and the film can make the diffraction phenomenon more obvious.
