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.

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.
Data Interpretation for an MMT assay: Absorbance (OD) values that are lower than the control cells indicate a reduction in the rate of cell proliferation. Conversely a higher absorbance rate indicates an increase in cell proliferation. Rarely, an increase in proliferation may be offset by cell death; evidence of cell death may be inferred from morphological changes.
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.

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.
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.
Not usually, but a decimetre is equal to 10 centimetres. The decimeter is a bit of a rarely used measurement.
It is rarely possible to measure anything with 100% precision, to the very last possible decimal place. We measure as accurately as we can, and we understand that the result is an estimation.
they only rarely determine when they happen, but they can measure how bad they are when or after they happen.
It is rarely, if ever reasonable. If a high level of accuracy is required then a micrometre is better.
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.
