What is the principle of 555 as Oscillator???
How we adjust the amplitude and frequency of the waves we got from this IC?

Google for "555 timer tutorial" for everything you want to know!.

This IC produces the waves from a RC circuit outside of the IC. Then a opamps inside makes the square wave.
The amplitude of the wave is the same of the power supply. To adjust the amplitude of the wave, adjust the power supply, and to adjust the frequency, adjust the resistor R in the RC circuit.

Good luck.

I would recommend Nigels method.
