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.
Refraction: light speeding up and slowing down, between mediums. When light travels from a more dense material to a low density material like glass to air, light will be refracted away from the normal. When light travels from a less dense material to high density material, for example from air to water, light will be refracted towards the normal. Similarly, the refracted ray is a ray that shows the direction that light travels after it has crossed over the boundary. In the diagram, a normal line is drawn to the surface at the point of incidence. This line is always drawn perpendicular to the boundary. The angle that the incident ray makes with the normal line is referred to as the angle of incidence. Similarly, the angle that the refracted ray makes with the normal line is referred to as the angle of refraction. The angle of incidence and angle of refraction are denoted by the following symbols: = angle of incidence = angle of refraction --- = Normal 90'
Yes, light does slow down when it travels through matter, as it interacts with atoms and molecules in the material. This slowing down of light is responsible for effects like refraction and dispersion.
Light travels faster (up to the speed of light) in a vacuum, which is empty space. Light travels slower through a medium (matter).

The index of refraction of a material is related to the speed of light in that material. Ruby has a lower index of refraction than diamond because light travels faster through the ruby compared to diamond. This difference is due to the different arrangement of atoms and the properties of the materials.
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.
When light travels from one material to another, it can be reflected, refracted, or absorbed. The degree to which each of these behaviors occurs depends on the properties of the two materials and the angle at which the light intersects the interface between them.
Light bends away from the normal (angle of incidence < angle of refraction) and travels at a faster speed in the medium with lower index of refraction.
The bending of light as it passes from one material to another is called refraction. Refraction occurs when light travels through materials of different densities, causing the light to change direction.
The index of refraction for glass is calculated by taking the speed of light in a vacuum and dividing it by the speed of light in glass. Since light travels 1.5 times faster in a vacuum, the index of refraction for glass would be 1 divided by 1.5, which equals 0.67.
The bending of light at the edge of a material is called refraction. This phenomenon occurs due to a change in the speed of light as it travels from one medium to another with a different optical density, causing the light rays to change direction.
It's 1/0.8 = 1.25
no, no material particle can approach the speed of light.
When light travels into a denser material, such as glass or water, it slows down and bends towards the normal, not away. This phenomenon is known as refraction.
