d A person with a height of 1.4 meters stands at the edge of a lake that is 2.8 meters deep, d = 2.8 m. A snapping turtle appears to be 3.4 meters from the edge of the lake. Note that the dotted lines show were the light appears to be originating, that is, where the image of the turtle is formed. The light is coming from the turtle, through the water, refracting into the air, and then to the person on the shore What is the angle of refraction for the light . degrees Submit Answer Tries 0/2 The index of refraction for the water in this lake is n = 1.4. What is the angle of incidence? degrees Submit Answer Tries 0/2 What is the distance from the edge of the lake to the point where the light is crossing from the water into the air? meters Submit Answer Tries 0/2 What is the actual distance from the lake edge to the turtle? meters Submit Answer Tries 0/2

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.
