Question

Write briefly one method each, of the production and detection of these radiations.

Hint:

Infrared radiation is commonly detected using thermal imaging techniques, while ultraviolet radiation detection often involves fluorescence or special photodetectors sensitive to UV wavelengths.

Answer 1

Step 1:
Production of Infrared Radiation: Infrared radiation is produced by heating an object or through the vibration of molecules. A common method of producing infrared radiation is by using an infrared lamp, which heats a filament to emit infrared radiation.
Detection of Infrared Radiation: Infrared radiation can be detected using an infrared sensor or an infrared camera, which measures the heat emitted by objects. Step 2:
Production of Ultraviolet Radiation: UV radiation is typically produced by special UV lamps or mercury vapor lamps, which emit UV light when an electric current passes through a gas or vapor.
Detection of Ultraviolet Radiation: UV radiation can be detected using UV detectors or by observing its effects, such as fluorescence in certain materials. UV-sensitive photographic plates or photodetectors can also be used for this purpose.
