Please refer to part (b). Here, theta (the angle the incident ray makes with respect to the vertical) is 50.7 degrees. What is d (the distance between the ray emerging from the bottom of the glass and where the ray would have been if it had continued straight on with no glass to refract it)?
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.
![### Diagram Explanation and Transcription
The image consists of three diagrams labeled (a), (b), and (c). These illustrate the refraction of light as it passes through different mediums—air, water (H₂O), and glass.
#### Diagram (a)
- **Description**: A triangular glass prism with refractive index \( n_2 = 1.5 \) is shown, surrounded by air with refractive index \( n_1 = 1 \).
- **Components**:
- *Input Ray*: A light ray enters the prism parallel to the base.
- *Angle of Incidence (\(\alpha\))*: The angle of the prism where the light enters.
- *Refracted Ray (\(\theta\))*: The light ray is shown refracting at an angle inside the glass.
#### Diagram (b)
- **Description**: A rectangular block submerged in water, with water having a refractive index \( n_1 = 1.3 \) and glass with \( n_2 = 1.5 \).
- **Components**:
- *Ray Path*: A red ray enters water at an angle (\(\theta\)), refracts as it enters glass at a calculated shift (\(d\)), and exits back into water.
- *Dimensions*: The width of the block is 10 meters.
#### Diagram (c)
- **Description**: An inverted triangular glass prism with a refractive index \( n_2 = 1.5 \) surrounded by air.
- **Components**:
- *Input Ray*: A horizontal red ray entering the prism.
- *Angle of Incidence (\(\alpha\))*: The angle at the top of the triangle where the light enters.
- *Refracted Ray (\(\theta\))*: The ray bends as it exits the prism.
These diagrams visually represent Snell's law of refraction, which describes how light bends when transitioning between materials with different refractive indices. The red light rays illustrate the changes in direction due to refraction as they move through the different mediums.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Febeba814-a0a4-41d1-99a8-f82307b9875b%2F9382e416-8d6b-4abb-9fea-b3e7beef59b0%2Focbbz0d_processed.png&w=3840&q=75)
