Can anyone please tell me the proper definition for Wave motion ?

what do you mean by ' that's not your question '
I mean your question doesn't make sense. Wave motion is a sub-topic in the study of waves, but definition of wave motion is "movement of a wave".
If, however, you wish to know about transverse waves and longitudinal waves, I'd tell you that transverse waves = waves where the medium vibrates perpendicularly to direction of wave; so if the wave is traveling vertically, the medium vibrates horizontally and vice versa. On the other hand, longitudinal waves = waves where the medium vibrates parallel to the direction of wave; so if the wave is traveling vertically, the medium vibrates vertically too. All waves transfer energy in the direction of travel, without transfer of matter. All waves in OL are transverse except for all types of sound (sonic) waves, and seismic P-waves. As unplugged mentioned, v=fλ (speed = frequency x wavelength -- all in SI units) and v=d/t (speed = distance traveled / time taken) For echoes, distance traveled is twice the distance to the reflector, (or you can say that time is half the time taken to return) or v= 2d / t.
There's lots of other stuff, of course -- it would be useful to know what exactly you wish to know, so I can focus on it, rather than trying to summarize the entire topic.
