A light ray from water passes through a block of glass and finally emerges into air. The light is refracted as it passes through these media. What is true about the speed of light after it emerges from the block into air? n = 1.00 1/ I Air Glass n = 1.52 Water n = 1.33 None of the answer choices is correct. The speed is less than before it entered the block. The speed is the same as before it entered the block. The speed is more than before it entered the block. The speed never changes as it passes from air through glass.
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.
