Interference and diffraction of waves

Interference of waves is the superposition of two waves, with some areas strengthening and others weakening. Diffraction is the propagation of waves around obstacles, both of which are unique phenomena of waves and reflect their wave characteristics. The ground projection displays the light dark or strong weak distribution of interference formation rules, as well as the unique diffraction patterns generated by diffraction, both of which contain natural harmony and beauty.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

In physics, interference refers to the superposition of two or more columns of waves in space, where their amplitudes and phases affect each other, resulting in a new wave phenomenon. When two waves have the same frequency and vibration direction, they will produce an amplitude addition effect in some areas and an amplitude subtraction effect in other areas. This phenomenon is called wave interference. two In classical physics, diffraction refers to the varying degrees of bending and scattering of waves after passing through obstacles such as narrow slits, small holes, or disks. Assuming an obstacle is placed between a light source and an observation screen, there will be bright and dark areas appearing on the observation screen, and the boundaries of these areas are not sharp, forming a complex pattern of alternating light and dark. This phenomenon is called diffraction.
