When she takes the white light through the prism, she knocks in seven colors. The Simplest Example of spectrometry is that under spectroscopy we study the internal structure of substances. It mainly studies the spectral. Spectroscopy is the study of interstellar matter between real substances and is also called spectroscopy. The foundations of spectroscopy were laid by Newton in 1666 AD. The beam of light coming from a window hole in a closed room to go through a prism to the screen and seven colors in the bandage - r, o, y, g, s, b, and p - were visible in this order.
