What is the unit of transmittance?
There is none.
Is transmittance a more accurate measurement?
Transmittance is a measurement of the amount of light that is able to pass through a material, and it can be used to accurately determine the amount of light that is transmitted. However, the accuracy of the measurement depends on factors such as the quality of the equipment used and the conditions under which the measurement is taken. Therefore, while transmittance can provide an accurate measurement, it is important to ensure that proper procedures and equipment are used to minimize errors.
How do you convert 008 to a percent?
To convert to percent, move the decimal two places to the right. If you mean .008, the percent is 0.8 %If you mean 8, the percent is 800%
What is the percent of 24.5?
If you mean 24.5 as a percent, then the answer is 24.5 times 100 or 2450 percent
What is 3.50 percent?
3.5 percent= .035 as a decimal and is 3 and 1/2 percent. If you mean what is 3.5 AS A percent, then it is 350%.
How do you convert percent transmittance to mgL?
how do you convert percent transmittance to mg/l
How can you figure out Absorbance without percent transmittance?
A=logIo/I
Does a higher percent of transmittance mean there is more aerobic respiration?
A higher percent of transmittance in a solution typically indicates that more light is passing through, suggesting lower absorbance by the substances present. In the context of aerobic respiration, if transmittance is measured for a product like carbon dioxide or a byproduct of respiration, a higher percent could imply more aerobic respiration is occurring. However, transmittance alone doesn't directly measure respiration; it must be considered alongside other factors like the specific substances being analyzed.
What is the relationship between absorbance and transmittance?
Absorbance = -log (percent transmittance/100)
Light transmittance can be more then 100 percent?
logically no because if it is a yes, then the light reaching the detector is greater than the light which was produced by the machine in the first place. But you may get transmittance greater than 100 because some parameters of your experiment may not be right.
What reasons can you give for the difference in the percentage of transmittance between the live chlorplats that were incubated in the light and those that were kept in the dark?
The percent transmittance grew to steadily higher numbers as the experiment progressed because the light reaction was able to occur. However, the dark cuvettes had stable levels of transmittance because light is necessary to excite electrons, which, in turn, reduces the DPIP.
Why do ir spectra seldom show regions at which the transmittance is 100 percent?
IR spectra seldom show regions at 100% transmittance because most molecules absorb some infrared radiation due to their unique bond vibrations. Even if there are no absorptions in a particular region, factors like impurities, instrument noise, or scattering can lead to a lack of complete transmittance.
What happens to light that strikes clear plastic?
A common technique in chemistry is spectroscopic analysis. This is where light is passed through a solution to determine its composition. The spectrometer will give a reading of absorbance or percent transmittance. The absorbance tells you how much light is absorbed, while the percent transmittance tells you what percentage of the light passed through and was not absorbed. If when you say clear you mean "colorless," all the light will pass through. The plastic is most likely not entirely colorless so only a small portion of the light will be absorbed, and it will have a high percent transmittance value.
What is the unit of transmittance?
There is none.
What is the advantage of reading the absorbance rather than the percent transmittance on the spectrophotometer?
Reading absorbance values is advantageous because it provides a linear relationship with concentration, making it easier to quantify the amount of substance present in a sample. Percent transmittance, on the other hand, is a non-linear measurement that can be affected by factors like stray light, making it less accurate for quantitative analysis.
Why do chemists prefer to read the absorbance rather than the percent transmittance of lght when analyzing a sample having a visible color?
Chemists prefer to read the absorbance rather than the percent transmittance of light when analyzing a sample with a visible color because absorbance is directly proportional to concentration according to the Beer-Lambert Law. This allows for more accurate quantification of the sample's components. In contrast, percent transmittance may not provide a linear response and can be influenced by factors beyond just concentration, such as the color of the sample itself.
The lower transmittance of film indicates higher absorption or reflectance?
The lower transmittance of film would indicate a higher Optical Density (OD), or absorption, because as concentration increases, % transmittance will decrease. This is because of Beer's Law (A = 2.00 -[log (%T)]). As you can see from the equation, transmittance is directly proportional to the outcome of absorption. High %T = Lower Absorption.Low %T = Higher Absorption.
