a) The medium separated up into a number of components. Every part is vibrating up and down as a whole.
b) All the molecules in single particular segment vibrate in the same medium. Molecules in two consecutive segments vary in phase by 1800.
c) All the molecules except those at nodes, implement simple harmonic motion about their mean position with the similar time period.
d) The magnitude of vibration of particles differs from zero at nodes to maximum at antinodes (2a).
e) All positions pass their mean position twice in single time period.
