Detailed explanation-1: -A colorimeter can measure the absorbency of light waves. During colour measurement the change in the intensity of electromagnetic radiation in the visible wavelength region of the spectrum after transmitting or reflecting by an object or solution is measured.
Detailed explanation-2: -In a colorimeter, a beam of light with a specific wavelength is passed through a solution via a series of lenses, which navigate the colored light to the measuring device. This analyzes the color compared to an existing standard. A microprocessor then calculates the absorbance or percent transmittance.
Detailed explanation-3: -Photometer A photometer is an instrument that measures light intensity. It can be defined as an instrument that measures visible light.
