Ever experienced the voice of a highly trained singer break a wine glass? Or when a bridge you are walking on suddenly starts vibrating. These are the effects of a well known process called resonance. Every object vibrates, rather oscillates at a certain natural frequency. Frequency is the number of oscillations a wave creates per unit of time and amplitude is its maximum range, it is a measure of intensity, loudness or power of a wave such as sound wave.
