Answer

Infrared Radiation

Infrared radiation is a type of electromagnetic radiation that is invisible to the human eye, but can be detected through special devices. It has longer wavelengths than visible light, and shorter wavelengths than radio waves. Infrared radiation is given off by all warm objects, including the human body, and is commonly used in a variety of applications.

Properties of Infrared Radiation

Wavelength: Infrared radiation has wavelengths ranging from 0.7 micrometers to 1 millimeter.

Energy: Infrared radiation has less energy than visible light, but more energy than radio waves.

Penetration: Infrared radiation can penetrate certain materials, such as clothing, plastic, and glass.

Heat: Infrared radiation is associated with heat and is commonly used in heating applications.

Uses of Infrared Radiation

Thermal Imaging: Infrared radiation is used in thermal imaging cameras to detect heat signatures. These cameras are used in various applications, such as monitoring industrial equipment, detecting fires, and conducting search and rescue operations.

Remote Control: Infrared radiation is used in remote control devices, such as television remotes and garage door openers.

Heating: Infrared radiation is used in heating applications, such as infrared heaters and saunas.

Medical Applications: Infrared radiation is used in medical applications, such as infrared lamps for pain relief and infrared thermometers for measuring body temperature.

Security: Infrared radiation is used in security systems, such as motion detectors and night vision cameras.

Health Effects of Infrared Radiation

Infrared radiation can cause skin damage, such as burns and skin cancer, if exposure is prolonged. It is important to take precautions, such as wearing protective clothing and using sunscreen, when working with or being exposed to infrared radiation.

Answer

Infrared radiation (IR), sometimes referred to simply as infrared, is a region of the electromagnetic radiation spectrum where wavelengths range from about 700 nanometers to 1 millimeter . Infrared waves are longer than those of visible light, but shorter than those of radio waves. Correspondingly, the frequencies of IR are higher than those of microwaves, but lower than those of visible light, ranging from about 300GHz to 400THz.It is a natural part of the human environment and thus people are exposed to it in small amounts in all are as of daily life—for example, at home or during recreational activities in the sun. Very intense exposure, however, may result from certain technical processes at the workplace.Many industrial processes involve thermal curing of various kinds of materials. The heat sources used or the heated material itself will usually emit such high levels of infrared radiation that a large number of workers are potentially at risk of being exposed.Source : Google
