what is the relationship between turbidity and transmittance?

A clear specimen will yield 100% transmittance, while a turbid sample will deflect a considerable portion of the light rays and will have a lower percent transmittance. The greater the density, the lower the percent transmittance.

The higher the turbidity, the harder it is to see through the water. Turbidity measurements are reported in nephelometric turbidity units (NTU) or Jackson turbidity units (JTU). The two units are roughly equivalent and can be used interchangeably for field purposes.

when concave lens immersed in water the focal length of lens increases because focal length of lens is directly proportional to refractive index of medium and when immersed in water the medium become more dancer so its focal length increases.

And that's the difference between Opacity and Fill. The Opacity value controls the transparency of anything and everything on a layer, including layer styles. The Fill value, on the other hand, affects only the actual contents of the layer, which in my case here was the text.

Optical density (OD) is the degree to which a refractive medium retards transmitted rays of light while absorbance is a measure of the capacity of a substance to absorb light of a specified wavelength. ...

Although the three scales measure turbidity differently, they are essentially the same in value. 1 NTU = 1 FTU = 1 FAU. For practical purposes, the EPA limit for turbidity in drinking water is 1 FTU. Anything above 1 FTU should be treated.

Concentration effects the absorbance very similarly to path length. If the concentration of solution is increased, then there are more molecules for the light to hit when it passes through. As the concentration increases, there are more molecules in the solution, and more light is blocked.

The relationship between absorbance and concentration for a particular substance is given by the Beer-Lambert equation: A  E*l*C, where A is absorbance, E is the molar absorptivity (extinction coefficient) for the substance, I is the length of the light path through the solution and c is concentration.

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.

The refractive index of a medium (n) is equal to the speed of light (c) divided by the velocity of light through the medium (v). Rearranging the equation allows us to see the relationship regarding v. The lower the refractive index, the faster the velocity of light. Medium A has the smaller refractive index.

The sample particles, bacteria for example, will absorb some of the light. The amount of light that is absorbed increases with increasing numbers of bacteria in a predictable way. The relationship between absorbance and the number of absorbing sample molecules is expressed mathematically as the Beer-Lambert Law.

In contrast to optical density, absorbance measures the ability of a refractive medium or optical component to absorb light. Where optical density measures the speed of light passing through a medium, absorbance measures how much light is lost over the course of light's passage through the given medium. ...

In the case of a white object all wavelengths (colours) of light are reflected. This process is completely different from transmission wherein the atoms simply do not absorb the photons as their energy is too low. So while transparent materials transmit light, white materials reflect it.

There is a relationship between concentration and absorbance. This relationship is expressed by the Lambert-Beer law, which is more commonly known as Beer's law. This law states that the absorbance of a light absorbing material is proportional to its concentration in solution.

translucent is clear: when something allows no light to pass through, it is opaque. When something allows some light to pass through, it is translucent. If it allows all light to pass through, it is transparent.

The absorbance is directly proportional to the concentration (c) of the solution of the sample used in the experiment. The absorbance is directly proportional to the length of the light path (l), which is equal to the width of the cuvette.
