Most of us have seen the formation of ripples when a small stone (pebble) is dropped into a pond. The disturbances created by the stone in the water produces ripples which move outwards towards the shore of the pond.
\nIf you examine the motion of a leaf floating near the disturbance for a short while on a steady day, you would see that the leaf moves up and down about its original position, but does not move away or towards the source of disturbance. This indicates that the disturbance (such as a water wave) moves from one place to another, but the water is not carried with it. The water particles simply move up and down their mean positions.
\nThe formation of ripples on the surface of water is an example of wave motion.<\/p>\n
Wave Motion:<\/strong> The movement of a disturbance produced in one part of a medium to another involving the transfer of energy but not the transfer of matter is called wave motion.

\n(a) Points B, F and J are in the same phase \u2013 all lie on the crests.
\n(b) Points D and H are in the same phase \u2013 both lie on the troughs.
\n(c) Points A, E and I are in the same phase. All these points are just about to start their vibration in the upward direction from their mean positions.
\n(d) Points C, G and K are in the same phase. All these points are just about to start their vibration in the downward direction from their mean positions.<\/li>\n<\/ol>\n
\n(i) When a body repeats its motion continuously on a definite path in a definite interval of time then its motion is called periodic motion.
\n(ii) The constant interval of time after which the motion is repeated is called the ‘Time period of motion.’ (T)
\nExample:<\/strong> Time period of hour hand is 12 hours.<\/p>\n
\n(i) If a body in periodic motion moves along the same path to and fro about a definite point (equilibrium position), then the motion of the body is a vibratory motion or oscillatory motion
\nNote: Resultant force acting on the particle is zero in equilibrium condition.
\n(ii) It is to be noted here that every oscillatory motion is periodic but every periodic motion is not oscillatory<\/p>\nCharacteristics Of Wave Motion<\/strong><\/h3>\n
