They key to volume control is a variable resistor.
A variable resistor uses a resistance track with connections at both ends. There is wiper that moves along the track as the volume knob is turned. The tracks are usually rotary for volume knobs, or tracks for volume sliders.
The variable resistor may be used as a rheostat, which means that only two terminals are used (the wiper and one end of the track). By turning the knob, the wiper sweeps across the track, which will effectively vary the resistance from 0 to maximum. A rheostat is usually used to vary current so they would be useful for varying the brightness of a lamp. A variable resistor can also be used as a potentiometer, which uses all three connections (both ends of track and wiper). If you connect the track terminals across a power supply, then the wiper terminal is used to provide a voltage, which can be varied from 0 to the maximum (the supply voltage). Potentiometers are usually used for amplifiers.

More decibels means that the sound volume increases.
Intensity of sound is dealt as volume in case of radio sets. Intensity is directly proportional to the square of amplitude. So as volume is turned down, intensity is reduced and so the amplitude is decreased.
Increase the volume.
how do i increase the volume on my nokia 6085. I can barely hear it when it rings
The greater the amplitude of a sound wave the louder the sound.
No. The length of a sound wave is it's frequency. Volume will increase the wave's AMPLITUDE.
Increase the volume. Failing that, buy a new set.
It was when the air hit the wave and it move to another direction
You mean by the word 'volume' the intensity of sound wave. Intensity is directly proportional to the square of the amplitude.
The 'Loudness' of a sound wave is dependent on its Amplitude, hence why we have 'amplifiers' to increase the volume of something.
