1. Continuous spectrum: A continuous spectrum is a spectrum that shows an unbroken sequence of frequencies or wavelengths. It is produced when an object emits a wide range of electromagnetic radiation across the entire spectrum. For example, a hot, dense solid or liquid emits a continuous spectrum of light.
2. Emission spectrum: An emission spectrum is produced when an object emits light at specific wavelengths or frequencies. These specific wavelengths correspond to electron transitions within the atoms of the emitting substance. Each element has a unique emission spectrum that can be used to identify the element.
3. Absorption spectrum: An absorption spectrum is produced when an object absorbs light at specific wavelengths or frequencies. This occurs when atoms or molecules in the object absorb light energy, causing electrons to move to higher energy levels. The absorption spectrum shows dark lines or bands at the wavelengths that have been absorbed. Each element or compound has a unique absorption spectrum that can be used for identification purposes.
Name the three types of spectra and explain briefly the cause of these spectra?
