Q: What type of detector is commonly used in UV-Vis spectroscopy?
Solution: Photomultiplier tubes are commonly used as detectors in UV-Vis spectroscopy due to their sensitivity to low light levels.
Steps: 4
Step 1: Understand that UV-Vis spectroscopy is a technique used to measure light absorption in the ultraviolet and visible regions of the electromagnetic spectrum.
Step 2: Recognize that a detector is a device that measures the amount of light that passes through a sample.
Step 3: Learn that photomultiplier tubes (PMTs) are a type of detector that can detect very low levels of light.
Step 4: Know that PMTs are commonly used in UV-Vis spectroscopy because they are very sensitive and can provide accurate measurements.
