What color of light has the highest refractive index?

The refractive index is inversely proportional to the wavelength, so the shorter the wavelength (the higher the frequency, or the more "blue" the light) the higher the refractive index. Conversely, the longer the wavelength (the lower the frequency, or the more "red" the light), the lower the refractive index. Therefore as wavelength of blue in less the refractive index will be maximum. For more information, follow the related link below.


Is there any effect of wavelength on refractive index?

The refractive index depends on the wavelength of the radiation. Traditionally the sodium line NaD20 (589,3 nm) is used for measurements (20 is the temperature on the Celsius scale).


What are the factors that affect refractive index?

What is meant by vacuum wavelength?

Vacuum wavelength is the wavelength that is measured if the wave is passing through a vacuum. To get the wavelength in a medium you need to know the refractive index.


Is there any effect of wavelength on refractiv index?

Yes. Normally the refractive index is slightly different for different wavelengths.


What would be the wavelength if the violet ray passes through diamond?

The wavelength of a violet ray in vacuum is 400nm. The refractive index of diamond is about 2.42. Using the formula λ'=λ/n where λ' is the wavelength of the ray in a material, λ is the wavelength in vacuum and n is the refractive index of the material, we get λ'=165nm.


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!

The refractive index of water is 43 and for glass it is 32 with respect to airwhat is the refractive index of glass with respect to air?

"The refractive index of water is 4 / 3" means the refractive index of water with respect to air. "The refractive index of glass is 3 /2" means the refractive index of glass with respect to air. You change the question as ," what is the refractive index of glass with respect to water? The answer is it is the ratio of refractive index of of glass with respect to air to the refractive index of water with respect to air =( 3/2) divided by( 4/3) = 1.125
