The simplest instrument would be a prism. However, a "spectograph" is a word used to represent several different types of machines, usually used to separate incoming waves (such as light waves) into a frequency spectrum. A spectograph is sometimes called a "polychromator."

A prism can be used for splitting light into its constituent colors, but scientists tend to use a more precise instrument called a spectrograph.

Hope this helps: Mixing Colors Have you ever wondered what the world would be like if there were no colors? What if there were only a few colors? It would probably be a very boring world compared to the one we live in now. Everyday you are surrounded by many different colors that come in different shades and hues. These are the results of color mixing. Today, we are going to learn about two different types of color mixing: additive color mixing and subtractive color mixing. Mixing Color Lights Mixing color light is called additive color mixing because the combined colors are formed by adding light from two or more light sources, which will give more illumination than any of the lights by themselves. In other words, the brightness of the lights is added together. For example, adding green light and blue light produces cyan light, which is brighter than its two components. Like in painting, all colors of light can be made from mixing three primary colors. Do you know the primary colors for light? In painting, the three primary colors are yellow, blue, and red, but for light they are RED, GREEN, and BLUE. Red and green light make yellow light. Green and blue light make cyan light. Blue and red light make magenta light. What do you think Red + Green + Blue light make? What is the brightest color of light Mixing color lights is used in theatre performances to create a dramatic effect. It is also used in television and computer monitors to create the full range of colors that give you the colorful cartoons or video games that you see and play.

Spectroscope is a device that separates light into its different colors.
A spectrometer is used to measure different properties of light. Normally one is given a specific wavelength for the light measured when using this instrument.

White light consists of a mixture of many different colors. Each color will have different interference patterns, making observation difficult.
Newton's rings are caused by interference of light waves. When monochromatic light is used, then newton's rings are alternately dark and bright .When white light is used then a few coloured rings are visible.After that due to overlapping of rings of different colours , the rings cannot be viewed. The different colored rings are obtained because of different wavelength of colors. the order of colors depend on order of ring.
A spectroscope is used to view the basic colors of any source of light. It helps show the atomic makeup.
