WebThe eye doctor will then ask if the chart appears more or less clear when different lenses are in place.The results depend on your responses. Then, a device shines specialized light into your eyes and also determines your refraction. Responses from you are not needed. Each type of refraction have their own benefits. WebAbsolutely. For example: If light travels between water and glass then refraction as well as reflection occurs. When a light ray strikes the border that separates the to mediums, a part of that light ray is reflected back into the same medium it came from (in this case the medium is water).

WebFigure 1.12 (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. In this case, the light can reach the observer by two different paths, so the fish seems to be in two different places. This bending of light is called refraction and is responsible for many …
