A black body, at a temperature of 227ºC, radiates heat at a rate ...
°C, emits radiation predominantly in the infrared region of the electromagnetic spectrum. This is because the peak wavelength of radiation emitted by a black body is inversely proportional to its temperature according to Wien's displacement law.
At 227°C, the black body emits a significant amount of thermal radiation in the form of infrared light. Infrared radiation has longer wavelengths than visible light, ranging from approximately 700 nanometers to 1 millimeter. This type of radiation is not visible to the human eye but can be detected and measured using specialized equipment such as infrared cameras and sensors.
Infrared radiation has various applications, including thermal imaging, remote sensing, and communication. It is commonly used in night vision devices, weather forecasting, and even in cooking (e.g., microwave ovens). Additionally, infrared radiation is also emitted by warm objects in our daily lives, such as our bodies, electrical appliances, and even the Earth's surface.
