Helppp.
Write down the definitions of these phenomena: interference, diffraction, dispersion and polarization. Explain in your own words what these phenomena are. Give at least 3 examples where we can observe them.
Sorry for my bad English

A] Interference is the act of or something that obstructs or hinders.
An example of an interference is a detour on the road. Thin film of a soap bubble (illustrated in Figure 1), which reflects a spectrum of beautiful colors when illuminated by natural or artificial light sources.
B] Diffraction is the slight bending of light as it passes around the edge of an object. The amount of bending depends on the relative size of the wavelength of light to the size of the opening. ... Optical effects resulting from diffraction are produced through the interference of light waves.
Example : The most colorful examples of diffraction are those involving light; for example, the closely spaced tracks on a CD or DVD act as a diffraction grating to form the familiar rainbow pattern we see when looking at a disk.
C] Polarization is a concept that comes from science, and it involves light, radiation, or magnetism moving in specific directions. ... Outside science, polarization usually refers to how people think, especially when two views emerge that drive people apart, kind of like two opposing magnets.
Common examples of surfaces that reflect polarized light are undisturbed water, glass, sheet plastics, and highways. In these instances, light waves that have the electric field vectors parallel to the surface are reflected to a greater degree than those with different orientations.
Hope this answer will help you.
