1. Everyone knows that opening one's eyes underwater results in blurred vision. Blurred vision is a result of the retina not being at the position where the image lands (i.e. it is either too close or too far from where the light is refracted). In the two diagrams given, the cornea of an eye is represented by a curved surface. In the left diagram, the incoming light ray is in air and is horizontal. The dotted line is perpendicular to the curved surface, and makes an angle of 40° with the horizontal axis. air, n = 1.00 40° cornea, n = 1.38 water, n = 1.33 40° cornea, n = 1.38 a. Sketch the path of the ray after it enters the cornea for both cases. b. Calculate the angle the ray inside the cornea makes with the dotted line in both cases.
Refraction of Light
Refraction is a change in the direction of light rays when they travel from one medium to another. It is the bending of light when it goes through different media.
Angle of Refraction
Light is considered by many scientists to have dual nature, both particle nature and wave nature. First, Particle nature is one in which we consider a stream of packets of energy called photons. Second, Wave nature is considering light as electromagnetic radiation whereas part of it is perceived by humans. Visible spectrum defined by humans lies in a range of 400 to 700 nm wavelengths.
Index of Refraction of Diamond
Diamond, the world’s hardest naturally occurring material and mineral known, is a solid form of the element carbon. The atoms are arranged in a crystal structure called diamond cubic. They exist in a huge variety of colours. Also, they are one of the best conductors of heat and have a very high melting point.
