1-Definition: It is the wave in which the It is the waves in which the
particles of the medium vibrate particles of the medium
perpendicular to the direction vibrate in the same direction
of the wave propagation. of the wave propagation.
-During wave propagation the
particles of the medium don't
change position but they
vibrate around point of rest.

and troughs compressions and rarefaction.
Crest: It is the highest Compression: It is the point

3-Wavelength It is the distance between two It is the distance between the
successive crests or troughs centers of two successive
compressions and rarefaction.
