Question

what is a longitudinal wave? In which medium: solid, liquid or gas, can it be produced?

Answer 1

longitudinal wave. A wave that oscillates back and forth on an axis that is the same as the axis along which the wave propagates. Sound waves are longitudinal waves, since the air molecules are displaced forward and backward on the same axis along which the sound travels. Compare transverse wave.. In a longitudinal wave, the particles of the medium move parallel to the wave's direction of travel. ... While transverse waves have crests and troughs, longitudinal waves have compressions and rarefactions. A compression is where the density of the wave medium is highestlongitudinal wave can travel through solids, liquids and gases, transversewaves can only travel through solids.
