Part A: Explore the Spectrometer
Notes: A spectrometer is a lab experiment primarily used for separating and measuring the spectral components of a particular physical phenomenon. In a broader, sense, the spectrometer is a series of instruments that help measure continuous variables of given phenomenon. It may separate the different components of white light under certain conditions, helping us measure the narrow bands of color, also known as spectrums.
