What does light bend when it passes from air into glass?
refraction
Why was density needed?
TO know about refraction of light and by the way it is still needed.......................
What is the name of the effect where light rays are bent as they enter a medium with a different density?
Refraction
The bending of a light ray as it passes from one substance to another one with a different density?
Refraction
When a light wave enters into a medium of different optical density?
index of refraction ( or refractive index)
How does light travle in a material with a higher index of refraction?
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).
Why is refractive index of light necessary?
it is necessary to identify the optical density of a particular medium air for example is 1.00 and the refraction in a medium can be figured out by sinøincidence ÷ sinø refraction
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. 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.

Will a given volume of a substance with low density be heavy or light?
Light.
Optical density formula?
Optical density is the same in SI as in other system of units, since it is a dimensionless number. It is called the index of refraction, and can be defined as the speed of light in a vacuum divided by the speed of light in the material in question.Optical density is the same in SI as in other system of units, since it is a dimensionless number.
