Visible Light and Color Properties

The video tutorial explains visible light within the electromagnetic spectrum, focusing on how white light is split into different colors by a prism, forming the colors of the rainbow. It details the order of these colors, known as ROYGBIV, and discusses the wavelengths and frequencies associated with each color. The tutorial also covers how to measure wavelengths and their inverse relationship with frequency, emphasizing that red has the longest wavelength and lowest frequency, while violet has the shortest wavelength and highest frequency.
