If the index of refraction of a medium is 1.4 determine the speed of light in that medium?
Speed of light in air (which has an index of refraction of 1) is 3 * 10^8 m/s. So divide the speed of light by the index of refraction of the new medium to obtain the speed of light in that medium. Hope I helped!!
Calculation of the speed of light?
I'll assume that this is the critical angle from the median to a vaccum. You use Snell's law, n1sin(x1) = n2sin(x2) where n1 = index of refraction of your median, n2 = 1 (the index of refraction in a vaccum), x1 = the critical angle (45 degrees), x2 = 90 degrees since light comes out at 90 degrees when it is shone on the critical angle. So... n1sin(45 degrees) = 1 (sin 90 = 1) n1 = 1/sin(45 degrees) n1 = 1.414... Now the index of refraction is the speed of light in a vaccum over the speed of light in the median so: 1.414... = (3.00 x 10^8 m/s) / v v = (3.00 x 10^8 m/s) / 1.414... v= 2.1 x 10^8 m/s
The speed of light in a particular type of glass is 1.60 X 108 What is the index of refraction of the glass?
The index of refraction, or optical density, is the ratio of the speed of light in a vacuum to that in a given material. Therefore, the index of refraction for this glass is equal to c / v = (3.0 x 10^8 m/s) / (1.6 x 10^8 m/s) = 3.0/1.6 = 1.88
What is the relation of the index of refraction glass to air?
1.5^-1 refractive index of glass to air=Speed of light in glass/Speed of light in air = 2*10^8/3*10^8=1/1.5=1.5^-1
Does the principle of optical reversibility hold for reflection as well as refraction?
Here's the way I see it: Optical reversibility means that if a light passes through a medium with an index of refraction, n, and the light hits that medium at a certain angle, the angle of incidence, the light refracts and comes out at a different angle than the angle of incidence. In other words, if light hits a refracting medium at 10 degrees to the normal, it will refract and come out at 7 degrees to the normal. Then, if it were switched, and the light were made to hit the refracting medium at 7 degrees to the normal, then it would refract and come out at 10 degrees to the normal. This is optical reversibility as seen in refraction. In reflection, however, the angle of incidence and the angle of reflection is the same. If light hits a reflecting medium at 10 degrees, it will reflect at an angle of 10 degrees. So if the angles were switched in this case, it would do nothing, it would just hit the reflecting medium at 10 degrees and again be reflected at 10 degrees. So, does the principle of optical reversibility hold for reflection as well as refraction? It depends on if you view switching the position of the same number to be reversing anything or not. Actually the principle holds good for every optical system in geometric optics....
If light passes through a medium at a speed of 2.5 x 10 to the 8 power meter per second what is its index of refraction?
my answer is 5
What is the speed of light while traveling through air at 30 degrees celsius?
When you look at a pencil in a cup of water and see a distorted image of the pencil it is called "Refraction". I have seen many people post statements saying light is not affected by temperature. This is incorrect. A mirage on the highway is a perfect example. Mirages are caused by hot air near the ground refracting, or bending, light rays upwart into the eyes of a distant observer. Speed of light in a vacuum = 3.00 x 10^8 m/s Refraction of Air at 30oC = 1.00026 Formula: n = c/v v = 3.00 x 10^8 / 1.00026 v = 2.99 x 10^8
In what medium the speed of light will be minimum?
The speed of light is a set speed at which all electromagnetic waves travel at in a vacuum. It is 3*10^8 meters/second... That being said, when light, or any other EM wave, travels through a medium it will slow down. Every material has an index of refraction which is the ratio of the speed at which light travels in a vacuum, to the the speed it travels in that material. If you know the index of refraction, you can use Snell's law to determine the speed light will travel through a specific medium. Every medium is different, however a rule of thumb is the denser the medium, the slower light will travel through it. For example, light travels faster in the atmoshpere than it does in water.
What is the speed if light?
Speed of light is 3.00 x 10^8.
What to wear at 10 degrees Celsius?
A light jacket. 10 degrees Celsius is 50 degrees Fahrenheit.
What is the speed of light through water and why?
To calculate the speed of light in any medium (like water) start with the speed of light in a vacuum (exactly 299,792,458 meters per second) and divide it by the index of refraction of that media. In most cases you can round off the speed of light to 299,800,000 meters per second. The index of refraction of water is about 1.33; so the speed of light in water is about 225,400,000 meters per second.
