Turbidity measures the degree of light is scattered by suspended particulate material and soluble colored compounds in the water.
Absorbance measures the amount of light absorbed by the constituents in the water with a specified wavelength.

What is the difference between absorbance and transmittance?
Transmittance is the ratio of light energy that is falling on a body. Absorbance is how much light energy is actually going into the body.
What is the purpose of wavelength scan?
Wavelength scans measure the absorbance and emission of light through a sample. Absorbance is proportional to concentration and a wavelength scan can be used to determine concentrations of a sample.
Can turbidity be used for testing milk?
i believe so , {yes}
In a plot of absorbance vs concentration what does the slope represent?
The slope of absorbance vs concentration reptresents the value of εb, where ε is the absorbtivity with units of (L/mol cm) and b is path length measured in cm.
What is the difference between clucth and coupling?
difference between clucth and coupling
What is difference between specific absorbance and absorbance interms of spectroscopy?
specific absorbance- it is absorbance in a solution containing one gm of substance in 100 ml solvent in 1cm shell. so it is having a difference with absorbance which is negative logarithm of incident light to the transmitted light. divya.chakraborty@gmail.com
What is difference between suspended solid and turbidity?
what is the difference b/w suspended solid & turbidity
What is the difference between spectrophotometer and fluorimeter?
A spectrometer shoots light through a sample and detects absorbance while a fluorimeter detects the intensity of fluorescence of a given sample.
What is the difference between absorbance and transmittance?
Transmittance is the ratio of light energy that is falling on a body. Absorbance is how much light energy is actually going into the body.
What is the different between primary absorbance and secondary absorbance in fluorescence?
in primary light absorbed by outer molecule while in secondary re-absorbance occurs
Is absorbance and OD the same thing or any difference?
there the same
What is the relationship between absorbance and transmittance?
Absorbance = -log (percent transmittance/100)
Is wavelength or absorbance the dependent variable?
"absorbance"Since in the experiment, you probably choose the wavelength, then measure the absorbance (absorption?, the absorbance is the dependent variable.
What causes turbidity in lagoons What is the reliability of turbidity data?
turbidity is pollution, thus runoffs and fertilizer and anything that makes up pollution is turbidity.
Why the value of absorbance is always between the 0-2?
It's over 9000.
What is the purpose of the blank?
Blank Sample in Spectrophotometry is used to measure the absorbance of light without sample. It is subtracted from the total absorbance for measurement of Absorbance from a sample's absorbance.
What is the purpose of blank samples?
Blank samples are used to establish a baseline measurement of background contamination in an analysis. By analyzing a blank sample containing no target analytes, researchers can identify and account for any background signals or contamination that may affect the accuracy of their results.
