How does cuvette size affect absorbance?
How does cuvette size affect absorbance? The absorbance is directly proportional to the concentration (c) of the solution of the sample used in the experiment. The absorbance is directly proportional to the length of the light path (l), which is equal to the width of the cuvette. How much should you fill a cuvette? Fill […]

How do you calculate lumens per watt?
How do you calculate lumens per watt? For example, a 100 W incandescent bulb produces about 1,600 lumens, for an efficiency of 1,600/100 = 16 lumens per watt. A halogen bulb, on the other hand, consumes only 72 watts for the same amount of brightness, making its efficiency 1,600/72 = 22 lumens per watt. How […]
