The prism is an optical device which offers different refractive index for different colours. If we take the case of white light which consists of "VIBGYOR". The red light will have less refractive index when compared to Violet or Blue colurs. The refractive index depends on the wavelength of the incident wave. If the wavelength is more , refactive index is less and vice versa.

∙ 9y agoThe refractive index give indications about the propagation of a radiation through any medium.
The formula is:
n=c/v where:
- c: speed of light in vacuum
- v: sped of light in a specified medium

∙ 13y agoThe index of refraction of a substance is
(speed of electromagnetic wave in vacuum) / (speed of electromagnetic wave in the substance).
Since the index is the ratio of two speeds, it has no units, and it's just a dimensionless number.

How can the index of refraction for different substances be determined mathematically?
n(index of refraction) = c(speed of light in a vacuum)/v(speed of material in the sebstance)
What is the bending of light rays as it passes from one material into another?
Index Of Refraction
When light passes from a medium with a high index of refraction into a medium with a lower index of refraction which direction does the light bend?
A medium with a higher index of refraction, like diamond, is more dense than the medium with a lower index of refraction, like air. If the ray of light is moving from the less dense medium (lower index of refraction), to a more dense (higher index of refraction) the ray of light bends TOWARDS the normal.
What is the refractive index for araldite CY 230 and HY 951?
The refractive index of Araldite CY 230 and HY 951 is typically around 1.54.
What is phase change in light of wavelength 600-NM incident in a material with index of refraction n equals 1.38 when it reflects from a material with index of refraction n equals 1.40?

How is the refractive index of glass is to water is related with that of air is to water?
Each substance has an index of refraction. The index of refraction of water is about 1.3330 . The index of refraction of air at standard conditions is about 1.0003 . There is no such thing as the index of refraction of "water to air".
When the mineral uvarovite has an index of refraction of 1.86. calculate the speed of light in this sample of uvarovite?
Use the definition of "index of refraction". In this case, you simply need to divide the speed of light in a vacuum by the index of refraction.
