What are 3 uses of infrared radiation?
Infrared (IR) light is used by electrical heaters, cookers for cooking food, short-range communications like remote controls, optical fibres, security systems and thermal imaging cameras which detect people in the dark.
What are 3 sources of infrared radiation?
Wavelength range and sources Common natural sources are solar radiation and fire. Common artificial sources include heating devices, and infrared lamps used and in the home and in infrared saunas for health purposes. Industrial sources of heat such as steel/iron production also fall into the infrared region.
How is infrared radiation used in everyday life?
The most common use of infrared in everyday life is remote controls. These work by sending pulses of infrared that spell out a message to an electronic device. This device could be a television, blu-ray player, or even a computer.
What is a detector of infrared radiation?
An infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic (photodetectors). The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena. Incident IR photons can cause electronic excitations.
What type of detector detects IR radiation?
8.2. There are currently two types of radiation detectors that are commonly used to detect IR radiation: (1) thermal detectors, and (2) quantum detectors. The thermal detector is commonly referred to as the uncooled microbolometer because this detector does not need cooling for the operation of the IR camera.
What are some examples of visible light?
For example, the sun produces visible light. Incandescent light bulbs, fluorescent, and neon lights are other examples of visible light that we may see on a regular basis. Visible light is probably the most important of all electromagnetic waves for most of us.
What are examples of microwaves?
Examples of Microwaves
- Ovens.
- GPS.
- Wi-Fi.
- Bluetooth.
- RADAR.
- Communication Systems.
- Medical Equipment.
- Weapons and Military Equipment.
What are the types of IR detectors?
The two main types of detectors are thermal and photonic (photodetectors). The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena. Bolometers and microbolometers are based on changes in resistance. Thermocouples and thermopiles use the thermoelectric effect.
How is non-ionizing radiation different from X-rays?
Unlike x-rays and other forms of ionizing radiation, non-ionizing radiation does not have enough energy to remove electrons from atoms and molecules. Non-ionizing radiation can heat substances. For example, the microwave radiation inside a microwave oven heats water and food rapidly.
What kind of radiation makes up the electromagnetic spectrum?
Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation. The other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light,…
What kind of radiation is invisible to the human eye?
Infrared radiation or IR also referred to as infrared, is a region of the electromagnetic radiation spectrum where the range of wavelengths is from about 700 nanometers to 1 millimetre. It is a type of radiant energy that is invisible to human eyes but that we can feel as heat.
What are the characteristics of regions of infrared radiation?
Characteristics of Regions of Infrared 1 The wavelength ranges from 3 to 8 micrometres. 2 This is used in the chemical industry and in astronomy. More
