![]() The gathering of diverse emitted wavelengths contributes to the formation of an Emission Spectrum. The range of frequencies of Electromagnetic Radiation released by an atom or molecule when it transitions from a higher energy state to a lower energy one is known as the Emission spectra. The spectra are classified into two types: When electromagnetic radiation passes through a prism or grating, it is divided into lines representing different wavelengths. Read More: Lens Formula and Magnification Band spectra or molecular spectra, are created by molecules radiating their rotational energies.Band spectra are sets of lines that are so tightly spaced that each group seems to be a band-for example, a nitrogen spectrum.Line spectra are also known as atomic spectra because the lines indicate wavelengths emitted by atoms as electrons change energy levels.Line spectra are unique to the elements that produce radiation.Because a slit is utilized as the light-imaging instrument, these wavelengths appear as a sequence of parallel lines.The spectrum of incandescent gases is known as a line spectrum emitting just a few wavelengths.As all wavelengths are present, the spectrum of incandescent solids is considered to be continuous.An absorption spectrum is made up of portions of a continuous spectrum that have been absorbed by the medium through which the light has passed and the missing wavelengths appear as dark lines in between.An emission spectrum is made up of all the radiations emitted by atoms or molecules.Spectra can be categorized based on their origins, such as emission or absorption.A spectroscope is an instrument designed for visual inspection of spectra, whereas a spectrograph is an instrument that pictures or maps spectra. The intensity of light as it fluctuates with wavelength or frequency, as defined in physics. It entails breaking light, an electromagnetic radiation into its constituent wavelengths, called spectrum, just like a prism splits light into a rainbow of colors. The study of the absorption and emission of light and other radiation by matter is known as spectroscopy. ![]()
