Here the light rays change their medium, which means there is a change of density when it enters the diamond. In addition to this, the rays also undergo Refraction, as when the light rays enter the diamond, there is a change in the refractive index. The diamonds are cut to reflect most of the rays entering them. We all have seen diamonds, and they are so shiny and reflective. This causes to increase the day time by 4 minutes. This shift causes changes like, sunrise appears to be 2 minute early and sunset seems to be 2 minutes late. The displacement of sun is about half degrees. This Refraction occurs due to its density variation from higher altitude to lower altitudes. This happens because Refraction.Īpparent position of sun due to refraction Image Credit: “Sunrise” FotoArt MB CC BY-SA 2.0ĭue to atmospheric refraction the position of the sun seem to be displaced. We cannot see things correctly, even if we use crystal clear ice. Suppose we make crystal clear ice and try to see through it. So the refraction phenomena are seen because of the convex lens present in it. After that, our mind re-corrects the image through the brain’s nervous system. This happens because our brain interprets the image, and hence we see real images. And as we know, convex lenses converge the rays passing through them. When the bent rays fall on the retina of the eyes, it forms an inverted image. The light which get reflected and strike our eyes, goes through refraction as our eyes have convex lens. As we know, all objects do not have their light, and they get lit up by any energy source. And when light falls on the object, it reflects the light. The lenses present in our eyes are convex. Let us understand how Refraction takes place in the eyes. The lenses present in our eyes show the Refraction of light. Refraction of light is seen in a transparent digital video disk Refraction can be seen in our eyes.Refraction in concave and convex lenses.Refraction causes an apparent shift in the position at sunrise.Refraction cause apparent flattening of the sun at sunrise and sunset.Refraction can understood by the given refraction of light examples. Refraction is the phenomena in which a ray of light gets bent due to change in the medium density.
