Light Diffraction Party Glasses (3 styles)

Party glasses based on the principle of diffraction can be used to watch light shows, fireworks displays, parties, etc. You can see amazing visual effects by pointing your glasses at different light sources. ▼Love style https://www.youtube.com/watch?v=0BOp1SnkZ1g&t=6s https://cdn1.cybassets.com/s/files/5993/ckeditor/pictures/content_2ae76573-d65f-4793-adc0-0e6ff5a76699.jpg https://cdn1.cybassets.com/s/files/5993/ckeditor/pictures/content_7064479e-2e34-477a-84ad-88c8d4f5b680.jpg ▼Star style https://www.youtube.com/watch?v=22O2EvqpiHc https://cdn1.cybassets.com/s/files/5993/ckeditor/pictures/content_2540e356-02aa-4682-95b5-d2d8e602b503.jpg https://cdn1.cybassets.com/s/files/5993/ckeditor/pictures/content_d6abb196-8651-450e-9980-4d4182a02689.jpg ▼Money money https://cdn1.cybassets.com/s/files/5993/ckeditor/pictures/content_02ff4469-c5af-42ad-af8c-326e58d1169b.jpg https://cdn1.cybassets.com/s/files/5993/ckeditor/pictures/content_0fabe4b7-17c6-473b-a448-e77d8f313e95.jpg <Science Tips> Diffraction (English: diffraction), also known as diffraction, It refers to the physical phenomenon that waves deviate from their original straight-line propagation when encountering obstacles. Assuming that an obstacle is placed between the light source and the observation screen, there will be bright areas and dark areas on the observation screen. Moreover, the boundaries of these areas are not sharp, and are a complex pattern of alternating light and dark. In classical physics, waves propagate with varying degrees of bending and divergence after passing through obstacles such as slits, holes, or disks. Any wave has the inherent property of diffracting under appropriate circumstances. However, the extent to which waves are diffracted varies in different situations. If the obstacle has multiple densely distributed pores, it will result in a more complex diffraction intensity distribution pattern.
