The figure below shows a laser beam (1) incident on a block of acrylic glass, with an angle of incidence of 61.0°. The beam partially reflects from the surface (2) and partially transmits (3) a refracted beam into the material, with a refraction angle of 35.9º. The transmitted beam itself reflects off the bottom surface (4) and refracts again when it exits the material (5). The laser beam's wavelength is 632.8 nm. 1 5 (a) What is the speed of light (in m/s) in the acrylic glass? m/s (b) What is the frequency of the light (in Hz) in the acrylic glass? Hz (c) What is the wavelength of the light (in nm) in the acrylic glass? nm
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.
