sounds propagates and travels through air. and propagated through other media. and the vibration Complete back and fort movement of an object is called a wave.it is also a disturbance of energy transmitted through matter or space. there are two kinds of wave.
Mechanical wave is a wave that needs a medium to propagate. a wave Connot travel through empty space.
there are 2 kinds of mechanical wave
a.) Longitudinal wave is a wave that travel parallel to the motion of particles. b.) Transverse wave is a wave that travel perpendicular to the motion of particles.
Electromagnetic wave is a wave that passed through empty space.
the characteristics of waves are the:
a.) trough - the lowest part of transverse wave.
b.) crest the highest part of transverse wave.
there are also properties of wavve: 1.)wave length 2.)Frequency 3.) the speed of the wave 4.) amplitude ......
