Final answer:
A single beam spectrophotometer consists of a light source, monochromator, sample compartment, detector, and display unit. The light source produces a specific wavelength of light that passes through the monochromator and sample compartment. The detector measures the absorption or transmission of light, and the display unit shows the results.
Step-by-step explanation:
A single beam spectrophotometer is a device used to measure the absorption or transmission of light by a chemical substance. Its key components include a light source, a monochromator, a sample compartment, a detector, and a display unit.
The light source produces a beam of light of a specific wavelength, which is then passed through a monochromator. The monochromator selects a specific wavelength of light to pass through the sample.
The sample compartment holds the substance being analyzed. The light passes through the sample, and its absorption or transmission is measured by a detector. The detector converts the energy of the transmitted or absorbed light into an electrical signal, which is then displayed on the display unit.
