Infrared Wave Length & Working Range

In summary, infrared waves are a segment of the electromagnetic spectrum before visible light, with a lower frequency and higher wavelength. It is commonly known as heat radiation and is used in various technologies such as infrared receivers and transmitters. The working range of infrared includes short-wave, mid-wave, and long-wave bands, with specific frequencies and wavelengths. The far infrared can extend even further in certain applications.

What do you want to know about it (them)?

Infrared(I think that's what you mean by infarade) waves encompass the region of the electromagnetic spectrum right before light, commonly considered as heat radiation. As it is present right before light, it has a frequency that is a bit lower, and a wavelength that is higher as a result of the equation given in a post above. Due to the lower frequency, it also has less energy, also given in an equation in a post above.

Or, in less nerdy terms, infrared is the segment before light, with lower energy/frequency.

What do you mean by "working range"?

I want to know about the working range of Infrared receiver and transmitter and also if there is any type of IR transmitter just like as RFID Passive tag
 
  • #6


is the wavelength of light the frequency that it sends out photons?

what? makes no sense.

Infrared is the part of the EM spectrum between the upper end of visible and microwaves.
Roughly 750 nm to about 1 mm. I am sure there is some disagreement on the upper boundary, but long wavelength IR and microwaves have a lot in common.

Typically, short-wave infrared (SWIR) is from 0.7 um to 1.1 um, the part of the spectrum we can't see but that Si detectors can still respond to. Mid-wave (MWIR) is about 3-5 um and long-wave (LWIR) is 8-12 um: both bands are set by absorbance bands of water, and the MWIR and LWIR bands are within 'transmission windows'. Going out further, for example in FTIR measurements, the far infrared can go out to about 20um or more.
 

1. What is the definition of infrared wave length?

Infrared wave length refers to the length of the electromagnetic waves that fall within the infrared spectrum. These waves have longer wavelengths than visible light, ranging from 700 nanometers to 1 millimeter.

2. How does infrared technology work?

Infrared technology works by emitting and detecting infrared radiation. Infrared radiation is emitted by objects and this radiation is then converted into an electrical signal by the infrared sensor. The signal is then interpreted and displayed as an image or temperature reading.

3. What is the working range of infrared technology?

The working range of infrared technology depends on the specific device, but it typically ranges from a few centimeters to several hundred meters. The range is affected by factors such as the power of the infrared source, the sensitivity of the detector, and the quality of the optics.

4. How is infrared technology used in everyday life?

Infrared technology is used in a variety of applications in everyday life. It is used in remote controls, security systems, thermal imaging cameras, and medical devices. It is also used in agriculture, manufacturing, and astronomy.

5. What are the advantages of using infrared technology?

Infrared technology has several advantages, including its ability to detect heat signatures and temperature differences, its non-invasive nature, and its ability to work in low light or dark environments. It is also relatively inexpensive and can be used for a wide range of applications.
