It is the ratio between the speed of light in a vacuum, and the speed of light in the material. The angle at which light is refracted is related to the index of refraction, and can be calculated using Snell's Law.

What is materials index of refraction?
It's (the speed of light in vacuum)/(the speed of light in the material) .
What is the materials index of refraction?
It's (the speed of light in vacuum)/(the speed of light in the material) .
What is the angle or refraction when the angle of incidence is 40degrees?
That depends on the substances where the refraction occurs. The relationship between the angles, and the index of refraction of both materials, is given by Snell's Law.
What happen when light is directed at a transparent materials?
When light is directed at transparent materials, it bounces off of the particles and is refracted accordingly. This causes the light to bend according to the materials refraction index. The higher the refraction index of the material, and the thicker it is, the more it bends the light and separates the colors.
Will light bend if it enters a new material?
Yes. It depends on the angle of incidence and the details of refractive index of materials.
Why does the incident angle not equal the angle of refraction?
i=incidence angle, r=angle of refraction Refractive index= sini/sinr Since for different materials value of refractive index is different hence both angles are not equal.
Does the wavlength increase when a refraction of a wave occurs when the wave travels from one material into another?
The wavelength changes. Whether it increases or decreases depends on the index of refraction of both materials.
How do you think increasing a medium's index of refraction might affect the angle of refraction?

What is the bending of light rays as it passes from one material into another?
Index Of Refraction
What does refractive index mean?
The amount of refraction depends on the difference in density between two mediums. So, the amount of refraction a material has, or it's refraction index, is the amount light will bend as it goes from medium into another medium. For instance, Vacuum is considered to have a refraction index of 1 and all other materials being denser than vacuum will naturally have a larger refraction index, they bend light more. So, it simply means that- since the object has a high density it will slow down light by a greater amount.
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 physical significance of refractive index?
The amount of refraction depends on the difference in density between two mediums. So, the amount of refraction a material has, or it's refraction index, is the amount light will bend as it goes from medium into another medium.
