could you tell me why the fuems are formed in the water falls.what is the effect of vapour on this formation?is there any relation of solubility of air in water with this phenomenon?
<...is there any relation of solubility of air in water with this phenomenon?...>
The air in the immediate vicinity of the mist is likely to be fully saturated, i.e. up to 100% relative humidity.
The water that forms the mist is likely to have high levels of air dissolved in it.

sir,i meant the air bubbles formed when the water reaches ground(where the bubbles are large in number)From where the air bubbles are comming into the water.
If you stand next to a discharging sleeve valve of a storage dam you need to hold onto something because of the stream of air coming in from the side.
The spillway of a dam is also shaped so as to keep the flow of water not leaving the concrete and cause negative pressure.
At a waterfall with a sharp edge there would be a negative pressure at the lip causing air to be required there. The falling (accelerating) water also take some undissolved air with it.
At the bottom the water air mixture will plunge into the pool and the bubbles will rise again. Run a smooth flowing faucet into a bucket and note the bubbles even going down.
