When we drop a stone into a lake or pond the waves of circle shape is produce. Why it is produce in circle shape only Why not in other shape?
For short wavelengths, the surface tension term dominates, and we get capillary waves. For long wavelengths, gravity dominates, and we get gravity waves. In general, both effects matter, and this leads to an interesting effect.

waves travel in all directions ao it appears to be in the form of ripples or circum or circle like waves (transverse waves) on the surface of water

Heya friend!!!
Here is your answer....
_____________________________________________________________
there's one feature of these waves that is relatively simple.
Two effects dominate surface tension and gravity. The behavior also depends on the depth of the water and the densities of the air and water also matter, but for the case at hand, except at the edges of the lake (and as long as we're not dealing with a puddle), we can treat the depth of the lake as effectively infinite, and the density of air is so much less than the density of water that it has minimal effect.
The critical wavelength -- which is about 1.7 cm for water in a lake on Earth -- is the wavelength that moves out most slowly. That means that if you look around the where the pebble entered, you will see a clear circle around the pebble, expanding at the speed of these slowest moving waves.
