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).
No, light travels slower in a material with a higher index of refraction compared to vacuum or air. This is because the speed of light is inversely proportional to the index of refraction of the material according to the equation v = c/n, where v is the speed of light in the material, c is the speed of light in vacuum, and n is the index of refraction.

Yes, that is correct. The index of refraction of a material determines how much light will bend as it enters the material. A higher index of refraction means that the light will bend more as it enters the material.
The ray of light bends towards the normal.
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.
When the index of refraction of a material is higher, light slows down and bends more when traveling through that material. This causes the light to be more strongly refracted. When the index of refraction is lower, light speeds up and bends less, resulting in weaker refraction.
As the index of refraction of the bottom material increases, the angle of refraction will decrease. This relationship is governed by Snell's Law, which states that the angle of refraction is inversely proportional to the index of refraction. Therefore, higher index of refraction causes light to bend less when entering a denser medium.

A material's index of refraction is related to its optical density through Snell's Law, which relates the angles of incidence and refraction as light passes through the interface between two materials with different refractive indices. A higher index of refraction usually corresponds to a higher optical density, meaning that light travels slower through the material.
A material with a high index of refraction bends light more than a material with a low index of refraction. This means that light travels slower through the material and the material appears denser to light. Materials like diamond and glass have high indexes of refraction.
The index of refraction of a material is determined by its optical density, which is influenced by the speed of light through that material compared to the speed of light in a vacuum. The index of refraction may also depend on factors such as the material's composition, structure, and temperature.
Increasing the density of the material through which the light is passing can increase the amount of refraction. Additionally, increasing the angle at which the light enters the material can also increase the amount of refraction. Finally, using a material with a higher refractive index can lead to increased refraction.
No, different materials have different indices of refraction. The index of refraction is a measure of how much a material slows down light as it passes through it, and it varies depending on the material's composition and density.
The index of refraction of CR-39 lens material is approximately 1.498.
