1) After the last week of physics class, you start playing with lasers and your fish tank at home. You shine your laser of wavelength 405 nm through the flat face of the glass (a special glass with n=1.55) aquarium tank at an angle of incidence of 45°. ,a. Your laser outside the tank shines the light beam through the glass and into the water inside the tank. At what angle from the normal does the light enter the water? b. How would this angle change if the tank was made of diamond? C. How would the angle change if the tank was originally made of 20° C ice?
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.
