Infrared (IR) radiation is a segment of the electromagnetic spectrum that falls just beyond the visible spectrum. It is widely used in thermal imaging, remote sensing, and scientific research due to its unique interactions with materials.
Wavelength Characteristics:
- IR wavelengths are longer than those of visible light but shorter than radio waves.
- Infrared (IR) radiation is a segment of the electromagnetic spectrum with wavelengths from approximately 700 nanometres (nm) to 1 millimetre (mm).
General Understanding:
- Commonly known as infrared, this region lies just beyond the visible spectrum of light.
- Any object with a temperature above absolute zero emits infrared radiation.
Applications:
- Infrared radiation plays a crucial role in applications such as thermal imaging, remote sensing, and spectroscopy due to its unique wavelength range that interacts differently with various materials.
