Spec 20 measures absorption spectrum . Lambert Beer law is applicable for data we got using it.
We can use this for both colored and colourless solution.
So answer should be coloured liquid
Colourless liquid
Measuring Absorption spectrum.

Beer’s Law Objective : We will explore an application of absorption spectroscopy using calibration curves and Beer’s Law. Use the “LAB : HOW TO…” link from the class website if you need help with how to use balance, Bunsen burner… and such. Introduction: You may write this information in your lab notebook for your own reference. It can’t be cut and pasted. Different solutions have different spectral properties. In this portion of the experiment those properties will be utilized to...

A company produces a single product on three production lines
that use different equipment. The production manager is considering
changing the layouts of the lines and would like to know what
effects different layouts would have on production output. Suppose
that the manager measured the average output for each line over
three randomly selected weeks using each of the three layouts under
consideration. The output (in hundreds of units produced) was
measured for each line for each of the four...

7 points) From previous studies, it has been generally believed that Northern Hemisphere icebergs have a mean depth of 270 meters and a standard deviation of 20 meters. An environmental ist has suggested that global warming has caused icebergs to have greater depth. A team of scientists visiting the Northern Hemisphere observed a random sample of 41 icebergs. The depth of the base of the iceberg below the surface was carefully measured for each and the sample mean and standard...

Remove the rays from the simulation by clicking on them and then pressing Delete. Place a Point Source at (60,180) by clicking Point Source under Tools, then clicking the simulation at (60,180). Note that the location at which the rays converge is the same as it was using the principal ray method. This is, in fact, why we use the principal ray method: it generates the convergence point using comparatively few lines. As we know from Huygens's principal, every point...

From the given case study, a) Discuss why Myanmar should or should not use protectionist policies b) Choose a country that also has applied IIP in the past to evaluate its costs and benefits. Myanmar is working hard to make the difficult economic transition from its current status as a Least Developed Country to its once-held spot as one of the most developed Asian economies. Urged on by many international and domestic experts, sweeping liberalisation reforms are being pursued by...
