Just beneath the surface of some very placid water (n = 1.33), lurks a shark. A piece of meat is dangled above the water’s surface and at a considerable horizontal distance away from the shark, as shown above. You are having a discussion with your two friends about whether the shark will be able to see the meat. Friend 1 – says that the shark will not be able to see the meat. Friend 2 claims that the shark can see the meat, only the shark will perceive the meat to be higher than it is in reality. Which friend (if either) do you agree with? show diagram with explanation
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.
