Features
- 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.
