Webphotometer, device that measures the strength of electromagnetic radiation in the range from ultraviolet to infrared and including the visible spectrum. Such devices are generally transducers that convert an electric current into a mechanical indication—e.g., a pointer moving across a dial. The source of the current may be a selenium cell, which generates … WebConsequently, the pressure on the black side is larger than the pressure on the white side. So there is a net force that pushes from black to white. The radiometer will move from left to right. It explains why the radiometer does not work in a total vacuum. The air moves in a direction and by Newton’s third law in the radiometer.

WebWorking of Infrared Thermometers. Similar to visible light, it is also possible to focus, reflect, or absorb infrared light. Infrared thermometers employ a lens to focus the infrared light emitting from the object onto a detector known as a thermopile. The thermopile is nothing but thermocouples connected in series or parallel.
