Web25. jan 2024 · Atmospheric Refraction is the refraction of light while passing through the earth’s atmosphere. The earth’s atmosphere is made up of several layers consisting of various gases. These layers of the earth’s atmosphere have different density, and the density goes on increasing as the light reach the earth’s surface from space. Web26. sep 2024 · Refraction is responsible for a tremendous range of optical phenomena, from the action of lenses to data transmission through optical fibers. Figure 6.2.3. 1: (a) Looking at the fish tank as shown, we can see the same fish in two different locations, because light changes directions when it passes from water to air.
