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 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.


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 is the unit of transmittance?

There is none.


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.


What is the difference between 'transmittance' and 'transmission'?

In one narrow sense, they are exactly synonymous. If you mean "communication by means of transmitted signals," then either word is fine; they are interchangeable. But that's all. Each word has shades of meaning that do not overlap. Transmittance is a word used in Physics that means "The ratio of the radiant energy transmitted to the total radiant energy incident on a given body." You can't use the word transmission in that sense. Further, the word transmission has another connotation: the act of sending a message; causing a message to be transmitted." You should not substitute transmittance in that sense. And finally, the gearbox in your car is a transmission, not a transmittance.
