index of refraction ( or refractive index)
refraction, caused by the difference in the speed of light between two media
Its speed and wavelength change
The light ray bends when it enters a medium with different density. It either bends towards or away from the normal depending on whether the medium is more dense or less dense.
When light enters a different medium, the amount that the light is bent as it enters the medium is determined by the medium's index of..........=refraction
When light enters a different medium, the amount that the light is bent as it enters the medium is determined by the medium's index of..........=refraction
Because of bending of any wave, such as a light or sound wave, when it passes from one medium into another of different optical density.
Optical density is the measure of the transmission of an optical medium for a given wavelength.Higher OD lower transmittence and vice versa e.g; optical density of 1 means 90% of incident light is absorbed.Optical density is the absorbance of an optical element for a given wavelength λ per unit distance: Where: : l = the distance that light travels through the sample (i.e., the sample thickness), measured in cm Aλ = the absorbance at wavelength λ T = the per-unit transmittance I0 = the intensity of the incident light beam I = the intensity of the transmitted light beamoptical density is the measure of the transmition of an optical medium for a given wave length.
It changes, in accordance with the optical density of the medium.

The optical density of a medium is not the same as its physical density. The physical density of a material refers to the mass/volume ratio. Optical density determines how much a light wave is slowed down as it passes through a medium. The more optically dense a material is, the slower that a wave will move through the material.The refractive index is a measurement of optical density. A medium with a low optical density, would have also a low refractive index.For example air, having a low optical density has a refractive index of 1.0003, whereas water, with a higher optical density, has a higher refractive index of 1.333.

yes , if the light travel from less density to more density the speed will decrease , the direction will change depend on the entered angle

-- If you're talking about physical density, then a more-dense substance hasmore mass than a less-dense one has in the same volume.-- If you're talking about optical density, then a more-dense medium has ahigher refractive index (the speed of light is lower in it) than a less-dense one.Higher optical density does not necessarily also mean higher optical density,although I don't have a specific example to give you.
There's no reason to expect that the intensity of light must necessarily change when it enters a different medium.
