The Application of Wien’s Law

Wien’s Law is an equation used to determine the temperature of objects in space. It was formulated by Wilhelm Wien in 1893, and states that the peak wavelength of an objects thermal radiation is inversely proportional to its temperature in kelvin (K). This means that the hotter the object, the more energy it emits, and the shorter the wavelength of the radiation emitted (Winters, 2019). This law has a multitude of applications in astronomy and astrophysics. One of the most common uses is in determining the temperature of stars. By measuring the peak wavelength of light emitted from a star, astronomers can calculate its approximate temperature. This information can then be used to understand the star’s mass, size, age, and other characteristics (Bohlin, 2017). Wien’s Law has also been used to determine the temperatures of nebulae and interstellar clouds. By looking at the wavelengths emitted from these objects, astronomers can determine their temperature and get an idea of their structure and composition (Bohlin, 2017). Finally, Wien’s Law has also been applied to the study of black bodies. A black body is an object that absorbs all the radiation it receives, and emits it… Cont…
