Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves. Water, ...
Fran Scott and Greg Foot explore the science of sound waves through a series of fun experiments. How woodwind instruments make sound. videoHow woodwind instruments make sound Greg Foot and Fran ...
Counter-intuitively, we also blow on a fire (or use bellows) to make it burn better ... Using an air vortex cannon to focus the sound waves from the bass reflex port, it ‘wiggles’ the flame ...
When placed against the mouthpiece of the instrument the air inside begins to vibrate too, forming sound waves. To make different notes the amount of air vibrating inside the instrument has to be ...
