Infrared radiation. The infrared part of the electromagnetic spectrum covers the range from roughly 300 GHz to 400 THz (1 mm – 750 nm) . It can be divided into three parts: Far-infrared, from 300 GHz to 30 THz (1 mm – 10 μm).

The generally established audio frequency range is 20 Hz to 20,000 Hz , though most people can hear less than this entire range, and as they get older, the range tends to contract on both ends. The relationship between music and audio frequency is that each time you move up an octave, you double the frequency.

A high-pitched whistle, squeal, and a child’s voice are high-frequency sounds.
Read moreWhat is the low frequency range?
Low frequency (LF) is the ITU designation for radio frequencies (RF) in the range of 30–300 kHz . Since its wavelengths range from 10–1 km, respectively, it is also known as the kilometre band or kilometre wave. LF radio waves exhibit low signal attenuation, making them suitable for long-distance communications.
