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).
Radiofrequency Radiation (RF) Radiofrequency (or RF) Radiation refers to electromagnetic fields with frequencies between 300 kHz and 300 MHz, while Microwave (or MW) Radiation covers fields from 300 MHz to 300 GHz. Since they have similar characteristics, RF and MW radiation are usually treated together.
