Infrared Light. Infrared (IR) light is light with lower frequency (higher wavelength) than visible light. IR light has frequencies ranging from 3*1011 to 4*1014 Hz (300 GHz to 400 THz) and wavelengths from 7.5*10-7 m to 10-3 m (750 nm to 1 mm).
The frequency of radiofrequency electromagnetic radiation ranges from 30 kilohertz (30 kHz, or 30,000 Hz) to 300 gigahertz (300 GHz, or 300 billion Hz). Electromagnetic fields in the radiofrequency range are used for telecommunications applications, including cell phones, televisions, and radio transmissions.
