Intro to Quantum Mechanics I
A thermometer is an instrument used to measure temperature, typically consisting of a glass tube filled with liquid that expands or contracts in response to changes in heat. This device plays a crucial role in various scientific fields, including physics and engineering, by providing quantitative data on thermal conditions. In the context of blackbody radiation and the ultraviolet catastrophe, thermometers help in understanding how objects emit radiation based on their temperature, highlighting the relationship between thermal energy and electromagnetic radiation.
