Emitter of heat

WebAll physical bodies are able to absorb and emit e.m. energy and there is a relationship between temperature, which is a measure of the heat charge of the body (as voltage is for electricity), and the wavelength of energy that the body emits. As the temperature of the emitter rises, the dominant wavelengths grow shorter and the frequency goes up. WebAn infrared heater or heat lamp is a heating appliance containing a high-temperature emitter that transfers energy to a cooler object through electromagnetic radiation. Depending on the temperature of the emitter, …
