The definition of absorbance is A=log( I(0) / I), which is the logarithm (base 10) of the initial intensity of the light passed through the sample divided by the intensity of the light after it has passed through. Let's look at a few values of A and see what these values imply. If A = 0, then I(0) must equal I, which means the intensity doesn't change, which means no light is absorbed. If A = 1, then I(0) / I must equal 10. This means that 90% of the light was absorbed. If A=2, then I(0) / I must equal 100, and 99% of the light was absorbed. If A=3, then I(0) / I must equal 1000, and 99.9% of the light was absorbed. And so on. To measure A over a range of 0 to 2 means that the spectrophotometer must be able to measure light intensities as small as 1/100th of the max value. This is a range of 100x, which is about what you can expect with ordinary electronic equipment. Compare this range to the ranges on a voltmeter. My voltmeter has several ranges available. Each of them has a range of only 10x. Instead of building multiple ranges into your spectrophotometer, the manufacturer (to save you money) expects you to dilute your sample until it falls into the usable range of the device.

What is the name of caesium and bromine together?
This compound is called caesium bromide with the chemical formula CsBr.This is an ionic salt, having the density 4,44 g/cm3, melting point 636 oC, boiling point 1 300 oC.CsBr is rarely used as a beamsplitter in spectrophotometers.
Is greaten a word?
Yes, but it is rarely used. GREATEN : "to make greater" might also be expressed as "enlarge", "expand", or "inflate". To make a person greater would be to "aggrandize".

Meters or rarely centimeters.
What is the length of the sei whale?
Adult sei whales can measure to 64 feet. Newborns can measure to 14 feet. Sei whales can measure to 70 feet but rarely exceeds 65 feet mark.
What volume is grain measured in?
Grain is usually sold by weight or mass. An appropriate measure of volume would be the liter, but it is rarely used. A few countries use bushels.Grain is usually sold by weight or mass.

Are there decimeters on a tape measure?
Not usually, but a decimetre is equal to 10 centimetres. The decimeter is a bit of a rarely used measurement.
When is it reasonable to measure to the nearest sixteenth inch?
It is rarely, if ever reasonable. If a high level of accuracy is required then a micrometre is better.
Why are football and soccer fields measured differently?
if you want to find how they measure the fields, i have an answer for you. Since football is and American sport, it is measured in yards and rarely meters, and since soccer is a mexican sport they measure it with meters.
Do scientist use Celsius or Fahrenheit to measure temperature?
Scientists generally use Celsius (or Kelvin) to measure temperature, as it is the standard unit in the scientific community. Fahrenheit is rarely used in scientific studies or publications.
What is the dog that can not bark?
All dogs 'bark' to a greater or lesser extent. However, the Basenji, a hunting dog, very rarely barks though they 'yodel' or whine.
How do you relate O.D values of MTT assay to cell count?
The O.D values from an MTT assay are used to measure metabolic activity of cells, not cell count. Higher O.D values indicate higher metabolic activity in the cells, which can be related to cell viability or proliferation. To relate O.D values to cell count, one would need to establish a standard curve correlating O.D values to known cell counts.
