Definition: A spectroscope is a type of telescope that uses an optical instrument to observe light and other forms of electromagnetic radiation. It consists of a small mirror or prism, which is used to focus light onto a screen, where it can be read by an eyepiece or an objective lens. Spectroscopes can be used for both visible light and infrared radiation. They are commonly used in astronomy, astrophysics, and other fields that require high-resolution observations of the electromagnetic spectrum. Some examples
