What is a spectrophotometer and how is it used?
gpt
A spectrophotometer is an instrument used for measuring the absorption or transmission of specific wavelengths of light, and it is used by filling a cuvette with a sample liquid, placing it in the spectrophotometer, and measuring the transmission or absorption as a particular wavelength of light shines on the sample.
Explanation: The spectrophotometer works by shining light on a sample and detecting how much of the light is transmitted or absorbed, providing a reading of the characteristics of the sample.
