Figure 35.20 (Example 35.6) Light rays from a coin embed- ded in a plastic sphere form a virtual image between the sur- face of the object and the sphere surface. Because the object is inside the sphere, the front of the refracting surface is the interior of the sphere. 3.0 cm 2.0 cm
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.
A set of coins is embedded in a spherical plastic paperweight having a radius of 3.0 cm. The index of refraction of the plastic is n1 = 1.50. One coin is located 2.0 cm from the edge of the sphere (as shown). Find the position of the image of the coin.
