frequency response, the first example of harmonic movement is planets' revolution. 

vibrating means passing from zero to maximum to minimum values.

alternate signals can be generated through irradiation.

even athoms have spin number.

every movement can be associated to a frequency. even straight rectilineous movement is associated to "zero frequency".

as we travel in time and space frequency does exist.

studying frequency we can understand many things.

let's have an object let's change it's speed in module or direction.

let's project rotation into a synusoidal movement.

let's consider the object in three dimensions. it could have 3 or more ways of vibration (X Y Z) and harmonics for each direction.

every component affects th other two components : let's consider a pure sine wave and an object vibrating in three directions.

vibration is a near conservative movement in the sense that we have an initial impulse to modify a state of quietness to create an instability which for frequency response has to be compensated by an opposite state. energy can fade but original frequency can be hardly modified.

vibration has it's propagation speed and depends from thickness of the medium. the medium has even influence on the direction.

we presume that each action has an effect in space and time.

ACTION = SOMETHING WICH HAS POWER TO MODIFY THE SPACE AND TIME....LIKE PICKING ON A STRING
