B Time it takes to convert one form of energy to another?

How much time does it take to convert one form of energy to another. Say ball dropped from a height 'H' its PE convert to KE. Can it be be defined in a time frame?

Energy is conserved, so from one point of view its conversion is instantaneous, otherwise you would have instants where the total energy is not the same as the previous instant.

But I get the impression that this is not exactly what your question is about. If you are talking about the conversion of a certain amount of energy, then it depends on the process doing the conversion. Take for example a car, where chemical energy is transformed into kinetic energy when you accelerate. The rate of conversion from one form to the other will depend on how fast the motor is turning (among other things).

The time frame needed by the ball to fall the distance H.

There is no fixed relationship. The quantity that relates energy Transfer to Time is Power (Watts are Joules per second) and a device can have any power the designers choose, the only limit is practicability.

Energy is transferred in a progressive wave but does not get transferred in a stationary wave I think.

Simply, it depends on the specific problem

Half way down half of the PE has been converted to KE. When it hits the ground all of the PE will have been converted to KE. You can use the equations of motion to calculate how long it takes to hit the ground.

The lake behind a hydro electric dam contains a lot of potential energy. The time it takes to convert it all to electrical energy depends on how fast they let the water through the turbine.

The rate at which energy is converted is called Power. The SI unit of power is the Watt (which = one joule per second).
