Just an observation I made this monsoon,
When a raindrop falls on the ground its colour starts to fade, this may be due to the absorption of water by the ground.
But gradually the radius of the water on the ground starts to increase and after a certain time interval it decreases
The decrease may be understood as adsorption of water by the ground but how would you explain the increase in the radius of the drop?
Also is their any way we could mathematical(and graphically) express the increase and decrease in the radius of the drop?
