As shown in the figure below, two transparent polycarbonate plates, each 19.0 cm long, touch each other at the right end, but are separated by a thin cylinder with a diameter of d = 0.0580 mm at the left end. (The plates are surrounded by air.) Light consisting of two wavelengths, 400 nm and 600 nm, is incident on and normal to the surface of the plate, and is viewed by reflection. At what distance from the contact point is the next dark fringe? x mm
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.
