In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. Only acoustic waves that have frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of 17 meters (56 ft) to 1.7 centimeters (0.67 in). Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges.

Freq Physics explores the outer fringe of the physics world.  Join us on our journey to explore new discoveries and merge them with existing ideas and principles.  Although we discuss a variety of physics, our focus is our energy, vibration and frequency in honor of Nikola Tesla. 

"The day science begins to study non-physical phenomena, it will make more progress in one decade than in all the previous centuries of its existence."  - Nikola Tesla
