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.
![**Question 1:**
An expensive spotlight is located at the bottom of a gold-plated swimming pool of depth \(d = 2.50 \, \text{m}\) (see Figure). Determine the **diameter** of the circle from which light emerges from the tranquil surface of the pool.
\[ \text{________} \, \text{m} \]
**Diagram Description:**
The diagram shows a cross-section of a swimming pool with water. A spotlight is placed at the bottom of the pool and emits light upwards. The depth of the pool is denoted by \(d\). The light rays form a cone-like shape as they reach the water surface. The top of the diagram is labeled "Air," and the bottom is labeled "Water." The purpose of the diagram is to visualize how light travels from the spotlight to the air interface above the pool.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcd0a9c9c-b0c8-47bb-88dc-3ac08f167320%2Ff7fb7335-d8ae-4401-871e-9af32581cc8c%2Fgre4qad_processed.jpeg&w=3840&q=75)
