Acoustics



=Different waves travel in different speed for example Sound travels 330 meters every second and the radio waves travel at the speed of light (300.000)kilometers per second.= =Is the number of waves that pass a point pert second. Frecuency= cycles/time Hz= =Is the distance between matching points on a wave.= =Longitudinal waves vibrate to the parallel of travel of the wave.= =Transverse waves vibrate at right angles to the direction of travel of the wave.= = =
