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.
What else can I help you with?
What is the simple definition of optical density and how does it relate to the absorption of light?
Optical density is a measure of how much light is absorbed by a substance. It is related to the absorption of light because the higher the optical density, the more light is absorbed by the substance.
Is turbidity and optical density is same?
Turbidity measures the cloudiness of a liquid caused by suspended solids, while optical density measures the amount of light absorbed by a sample. They are related in the sense that turbidity can affect optical density measurements, but they are not the same. Turbidity is a measure of the scattering of light by particles in a sample, while optical density is a measure of the absorption of light by a sample.
What is the relationship between the optical density (OD) and absorbance in spectrophotometry?
In spectrophotometry, optical density (OD) and absorbance are directly related. As the OD increases, the absorbance also increases. This means that a higher OD value indicates a higher absorbance of light by the sample being measured.
Which doesn't belong and why magnification power of magnification resolution mass density?
Mass doesn't belong because it is a measure of the amount of matter in an object, while magnification power, resolution, and density are all related to optical properties or physical characteristics.
Do Light waves bend or refract at what between two media?
Light waves bend or refract when they pass from one medium to another due to a change in speed caused by the change in the medium's optical density. This bending of light is governed by Snell's Law, which describes how the angle of incidence and the angle of refraction are related to each other.
How is trignometry used in optics?
Optics deals with refraction - the bending of light rays as they go from a medium of one optical density to another - as in an optical lens. Given the refractive indices of the two materials, the angle of refraction is related to the sine of the angle of incidence.

Optical density is a measure of how much light is absorbed by a substance. It is related to the absorption of light because the higher the optical density, the more light is absorbed by the substance.
How is mass of an object related to its optical density?
The mass of an object is not directly related to its optical density. Optical density is determined by how transparent or opaque the material is to light. Mass, on the other hand, is a measure of the amount of matter in an object. They are two different properties of an object and are not inherently connected.

Does a substance having high optical density have to have a high physical density?
It's not necessary. If a compound has high optical density, it means that it absorbs more light at the given wavelength than some reference compound. There is no simple relation between density of matter and optical density. Even more I am pretty sure you can find a lot of compounds with lower densities (of matter) but having high optical density.
The bending of light as it passes into a transparent material of different optical intensity is known as?
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'

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).
Which doesn't belong and why magnification power of magnification resolution mass density?
Mass doesn't belong because it is a measure of the amount of matter in an object, while magnification power, resolution, and density are all related to optical properties or physical characteristics.
What is the difference between material density optical density?
I was also looking for the answer to this question. I decided to see what Wikipedia had to say about it, and found this: http://en.wikipedia.org/wiki/Absorbance This article kinda explains how they are related. Good luck!

What are the terms related to refraction of light?
terms realated to refraction of light are * interface * incident ray * refracted ray * point of incidence *normal *angle of incidence * angle of refraction *angle of deviation
