Problem 2: A light was made to pass through the bottom of a lake during a search and rescue operation. The ray light was angled at 40 at the top of the lake, and the light refracted at an angle of 21. a. What is the speed of the light in the liquid (na =1.0003)? b. The rescued victim appeared to be 2m below water surface. What is the real depth of the victim? c. If the victim was seen floating between the water surface and the lake floor, what is the actual depth of the lake?
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.
