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).
Radio frequency (RF) refers to the rate of oscillation of electromagnetic radio waves in the range of 3 kHz to 300 GHz, as well as the alternating currents carrying the radio signals. This is the frequency band that is used for communications transmission and broadcasting.
