wavelength in vacuum/ wavelength in material = n
650nm/450nm= 1.44=n
Refractive index of that material would be:
n = c / v,
approximately n = (3 * 108) / (1.24 * 108) = 2.42.

The substance's index of refraction isSpeed of light in vacuum / Speed of light in the substance
n(index of refraction) = c(speed of light in a vacuum)/v(speed of material in the sebstance)
1.5 no units (APEX)
It will usually change. Usually you would expect the speed to decrease, but note that the "optical density", i.e. the index of refraction, is not entirely related to the density (as defined by mass/volume).
The index of refraction.
Also 1.5. That's how the index of refraction is defined.

It's (the speed of light in vacuum)/(the speed of light in the material) .
It's (the speed of light in vacuum)/(the speed of light in the material) .
The substance's index of refraction isSpeed of light in vacuum / Speed of light in the substance
n(index of refraction) = c(speed of light in a vacuum)/v(speed of material in the sebstance)
1.5 no units (APEX)
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.
That is called the index of refraction.
That is called the index of refraction.
That is called the index of refraction.
