What is bi-quartz in polarimeter?
biquatr polarimeter consists of two half semicircular quartz crystals,each one of them with a different orientation..of the incident light one of the cyrstals turns the light in one direction and the other in the other direction. its used for laboratory puroes in polarimeter experiments to find the specific rotation of any optically active comound using polarimeter tube apparatus.
What will slow the speed of light through a material?
Yes, it is possible to slow light. While light does not need a medium through which to travel, it can be slowed when it is shone through various materials. If light is projected through a Bose-Einstein condensate, it slows dramatically to something on the order of tens or hundreds of meters per second. It is the velocity of light in vacuum, c, that is often given as the velocity of light, and it is this velocity that is usually meant when people are talking about relativity or about physics in general. When I was in college I conducted an experiment in which we slowed light to a few meters per second, using carbon gas frozen to -433 F so it is possible to slow down light
1600s Galileo attempted to measure the speed of light using blank?
Galileo attempted to measure the speed of light using lanterns positioned at known distances and observing the time it took for light to travel between them. He would uncover the lanterns simultaneously and use a telescope to try and detect any delay in the light reaching his eyes. However, his methods were not sensitive enough to accurately measure the speed of light.
When was the speed of light measured?
The speed of light was first measured in 1676 by Danish astronomer Ole Rømer using observations of the moons of Jupiter. Rømer's work provided the first quantitative estimate of the speed of light.
What is the index of refraction of a solid in which the speed of light is 1.943x10 rise to the power of 8mins per secs?
The index of refraction (n) of a medium can be calculated using the formula ( n = \frac{c}{v} ), where ( c ) is the speed of light in a vacuum (approximately ( 3.00 \times 10^8 ) m/s) and ( v ) is the speed of light in the medium. Given that the speed of light in the solid is ( v = 1.943 \times 10^8 ) m/s, the index of refraction can be calculated as follows: [ n = \frac{3.00 \times 10^8 , \text{m/s}}{1.943 \times 10^8 , \text{m/s}} \approx 1.54. ] Thus, the index of refraction of the solid is approximately 1.54.
How to calculate index refraction?
Index of refraction can be calculated using the formula n = c/v, where n is the index of refraction, c is the speed of light in a vacuum, and v is the speed of light in the medium. Just divide the speed of light in a vacuum by the speed of light in the medium to find the index of refraction for that medium.
The main factors that determine the speed of a wave in any particular medium are?
The speed of light in a vacuum will always be approximately 299,792,458 meters per second. However, light travels at slower speeds when propagating through mediums. The speed of light in a medium is determined by the mediums index of refraction. The index of refraction is calculated using the following equation:n = c / v;where "n" is the refractive index, "c" is the speed of light in a vacuum, and "v" is the speed of light in the medium.
What experiment did do to find the velocity of light?
Fizeau(french physicist) method, Foucault method, and Michelson method are the most important experiments that were done. It is very hard in laboratory to measure the absolute speed of light. But if we accept the value of speed of light in air, then we can use snell's law of refraction to find the speed of light in another medium. I am describing that here: Suppose light enters from air to another medium. Then absolute refractive index(RI) of medium = sin(i) / sin(r) RI = c/v Where i = angle of incidence r = angle of refraction C = speed of sound in air or vaccum(both are almost same) V = speed of sound in medium. Using these two equations we can find speed of sound in the given medium
What is the derivation of the speed of sound in a medium?
The speed of sound in a medium is derived from the properties of the medium, such as its density and elasticity. It is calculated using the formula: speed of sound square root of (elasticity / density).
Why is light refracted when it passes from light to water?
this is because when light is passing into a different medium, it will travel at a different speed. As a result, it bends (refracts). in this case, from air to water. The angles of refraction can be found using Snell's law n of medium 1 (sin theta) = n of medium 2 (sin theta) n of a medium is called the index of refraction, which you can find on the internet.
Can you explain the concept of light refraction using a single ray?
Light refraction is the bending of light as it passes from one medium to another, such as from air to water. When a single ray of light enters a different medium at an angle, it changes speed and bends, or refracts, towards or away from the normal line, which is an imaginary line perpendicular to the surface. This bending is due to the change in the speed of light in different mediums, causing the ray to change direction.
What travels faster through the same medium red light or violet light?
Red light and violet light travel at the same speed in a vacuum, however, they travel at different speeds relative to each other when traveling through any medium other than a vacuum.In most media, violet light has a higher index of refraction (usually denoted with the letter n) than red light. The higher the index of refraction, the slower the light goes compared to its speed in a vacuum. This relationship is governed by the following equation: v = c/n where v is the speed of light in a particular medium, n is the index of refraction of light in that medium, and c is the speed of light in a vacuum. Since red light has a smaller n than violet light in most media, red light travels faster than violet light in most media.The index of refraction is determined by solving Maxwell's equations for a particular frequency and a particular medium using specific boundary conditions.Read more at the link I provided below.http://wiki.answers.com/Q/Which_travels_faster_red_light_or_violet_light#ixzz17j1yTzi6
Which is a line of sight communication medium?
Optical fibers are a line of sight communication medium that transmit data using light signals that travel straight along the fiber. They are commonly used in telecommunications and internet services for high-speed data transmission.
Can you give me an example of a sentence using the word refraction and medium?
" The light is bent by refraction, caused by the medium through which it passes"
What is a Computer storage medium that operates using digitized beams of light?
CDRW and DVDRW
How is the speed of light measured using a microwave?
The speed of light can be measured using a microwave by sending a microwave signal from one point to another and measuring the time it takes for the signal to travel. By knowing the distance between the two points and the time it takes for the signal to travel, the speed of light can be calculated using the formula speed distance/time.
What can travel at the speed of light?
Nothing can travel at the speed of light, only light itself, the closest we have ever gotten to the speed of light is 99.9 %, we have accelerated particles at very very close to the speed of light using the LHC (Large Hadron Collider). The only thing that can go faster than the speed of light, is Space.
