How does refractive index vary with wavelength?
Part 1 - WHY does refractive index vary?The refractive index of a material is determined by how quickly light travels through it. Different wavelengths travel at different speeds, hence the refractive index varies with wavelength. This is known as (chromatic) dispersion.In glass, red light travels faster than blue light, which is why a prism can be used to split white light into a rainbow.Part 2 - HOW does refractive index vary? (ie. Define the relationship).Sorry - I haven't a clue. I'm looking for the answer as well!
What is the refraction index of glass?
1.33 The IOR of 1.33 is the common value for water at 0°C, and to me is not the common accepted value for glass. That being said, there are many different types of glass, and they all vary in IOR. However a common standard value for glass is 1.5
When light passes from a fast medium to a slow medium is it refracted towards or away from the normal?
Light is refracted away from the normal while passing from denser(slow) medium to a rarer(fast) medium.At one angle called the critical angle the angle of diffraction is 900.After this the ray diffract at an angle greater than 90 i.e. it comes back to the slow medium.Whereas from faster to slower medium the rays bend towards the normal.Thus avoiding the possibility of coming back to the slow medium.
What happens when a wave changes medium?
On passing from one medium to another, the frequency of any wave stays constant. The wavelength changes such that the new wavelength equals the old wavelength multiplied by the old refractive index divided by the new refractive index. Lnew = Lold x (Nold/Nnew) Where L is the wavelength and N is the refractive index. The refractive index is a property related to wave velocity, which will vary in different mediums.
What is the percentage of light that the colour black absorbs?
There are different shades that we will all perceive as black; the percentage will vary. For a given material, it will also depend on the exact mix of frequencies in the light. The general idea is that black absorbs most of the incoming light. Check the Wikipedia article on "Albedo" for some examples; fresh asphalt is one of the darkest, listed as having an albedo of 0.04 (that is, only 4% of the light is reflected).

Does refractive index vary with the angle of incidence?
No. The refractive index is an absolute measure that determines by how much the angle of incidence is different from the angle of reflection.
What is Refractive Index of hydrocarbon?
The refractive index of hydrocarbon depends on the specific hydrocarbon compound. Generally, hydrocarbons have low refractive indices since they are non-polar and have a simple molecular structure. The refractive index can be determined experimentally and may vary slightly depending on factors such as temperature and impurities in the hydrocarbon sample.
What is a disadvantage of a refractometer?
Refractometers are used to measure the of a pure substance or mixture. Every has a unique refractive index that can be determined accurately. Refractive indices vary with composition as well as wavelengths of light, and are usually noted along with their respective wavelengths.
How does the density of material affect the refraction of light?
No refraction is the measure of the speed that the light travels through the substance, optical density is a measure of how much it is absorbed. Refer to the related link in the Related Links section below.
What is the speed of light through a solid?
The speed of light through a solid will depend on its refractive index. Water ice has a refractive index (RI) of 1.31 and so light will travel at a speed of 228,850,000 metres per second. Germanium has a RI approx 4 and so the speed of light is 74,950,000 metres per second. Then there are opaque solids and the speed of light through these is 0.

How much does laser refractive surgery cost?
"Depending on where you live and where you get the laser refractive surgery performed, the price may vary accordingly. You should expect to pay between $1,500 and $3,000."
How much memory do photos take up on an iPod touch?
It depends, they vary from around 2mb to about 20mb depending on the amount of detail, colour and light.
Is it true or false that indications of a chemical change include light heat and gas production?
True. Chemical changes can vary from colour change to gas production.
Why do star twinkel?
The vast majority of stars have roughly constant brightness over short periods of time. The apparent twinkling of the stars is caused by variations in the refractive index of the atmosphere, caused by natural turbulence.There are however a very important class of stars, the Cepheid Variables, which regularly vary in brightness, and which are used to measure vast astronomical distances.
What colour is a frog?
the colour of a frog can vary, it can be green, brown, and all sorts of other colours
