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.
![**Problem Statement:**
A plate glass window (\(n = 1.5\)) has a thickness of 3.1 mm. How long does it take light to pass perpendicularly through the plate?
**Input Fields:**
- **Number:** [Input box for numerical response]
- **Units:** [Dropdown for selecting units]
**Explanation:**
To solve this problem, you need to calculate the time it takes for light to travel through a medium given its refractive index. Use the formula:
\( t = \frac{d}{v} \),
where \( d \) is the thickness of the plate and \( v \) is the speed of light in the medium. The speed of light in the medium is calculated as:
\( v = \frac{c}{n} \),
where \( c \) is the speed of light in a vacuum (\(3 \times 10^8 \, \text{m/s}\)) and \( n \) is the refractive index.
**Steps:**
1. Calculate the speed of light in the glass: \( v = \frac{c}{n} = \frac{3 \times 10^8 \, \text{m/s}}{1.5} \).
2. Convert the thickness from mm to meters.
3. Substitute the values into the time formula to find the result.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3f0a09bd-ef71-43b6-abcd-653755da1dfb%2F69d2c480-742a-40eb-ac0f-43831304b8f4%2Fh6r60qu_processed.png&w=3840&q=75)
