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.


How can you figure out Absorbance without percent transmittance?

A=logIo/I


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.


If the transmittance is 0.34 what is the absorption?

A=-logT A=-log 0.34 A= -0.4685


What is the relationship between absorbance and transmittance?

Absorbance = -log (percent transmittance/100)


If Cuvette 5 transmittance changed what is concluded?

27? lol 24!


What happens to results when the cuvette is not correctly placed?

You get no light transmittance or absorbance.


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 legit limit for window tint in Alaska?

Driver and front passenger side windows must allow 70% light transmittance Rear passenger side windows must allow 40% light transmittance


Why do too densely coloured samples fail to give proper results using spectrophotometer?

Because we measure transmittance in spectrophotometer and for densely coloured samples transmittance will be very less. So we will not get proper results for absorbance.


What is the advantage of reading the absorbance rather than the percent transmittance on the spectrophotometer?
