Unfortunately, as a text-based AI, I am unable to provide a visual diagram. However, I can describe the concept to you using text.
To understand how a pure spectrum and white light can be produced, we need to know that white light is a combination of different colors, while a pure spectrum consists of a single color only.
One way to produce a pure spectrum is by using a prism. When a narrow beam of white light passes through a prism, it gets refracted (bent) at different angles due to the varying speeds of different colors of light. This phenomenon is known as dispersion. As a result, the white light separates into its component colors, creating a spectrum. This spectrum ranges from red, orange, yellow, green, blue, indigo, and violet, often remembered with the acronym ROYGBIV.
Each color in the spectrum corresponds to a specific wavelength of light. For example, red light has a longer wavelength, while violet light has a shorter wavelength. By using a narrow slit or a narrow slit with a lens, we can isolate a particular color from the spectrum, creating a pure spectrum.
On the other hand, to produce white light, we need to combine all the colors of the spectrum. This can be achieved by passing each color from the spectrum (red, orange, yellow, green, blue, indigo, and violet) through filters and then recombining them. When all the colors are combined, they form white light. This process is commonly used in devices like LCD displays, where small red, green, and blue pixels combine to produce a full-color image.
Overall, a pure spectrum is produced by separating white light using a prism, while white light is produced by combining all the colors of the spectrum using filters or light sources like RGB LEDs.
