Examples of Wien’s Displacement Law
Examples of Wien’s Displacement Law include:
- Peak radiation from a wood fire that is around 1500K hot is produced at 2000 nm, as is evident. In other words, the majority of the radiation that the wood fire emits is not visible to the unaided eye. Because of this, a campfire is a terrible source of light while being a fantastic source of heat.
- When a piece of metal is heated, it first turns red hot. The longest wavelength in the visible spectrum is this one. The color shifts from red to orange to yellow with additional heating. At its hottest, the metal will shine white. The shorter wavelengths of light are dominant.
- In an Incandescent light bulb, the heat produced by the filament is directly proportional to the voltage, in the case of voltage drops temperature of the filament also drops with it. Which can be seen as the bulb looking red compared to its previous state.
Wien’s Displacement Law
Wein’s Displacement Law or Wein’s Law is named after the man who discovered it, Wilhelm Wien; a German physicist. Wilhelm Wein has done remarkable work in the field of Radiation, for which he was granted a noble price for physics in 1911. Max Planck who was a colleague of Wien, continued his work on the same topic and gave Wein-Plank Law and further a more general law Planck’s Law of Radiation. Wein’s Displacement Law is a fundamental concept in the study of radiation and describes the relationship between the temperature of an object and the wavelength of its maximum emission of radiation. This short article provides a thorough explanation of Wein’s law, including the mathematical formulation and various ways it can be expressed.
