Even if the excitation is very small, the object will vibrate strongly and deviate from a straight-frequency characteristic which is caused by size, shape or construction of a room or enclosure. Forced vibration in which the offense frequency is close to the natural frequency, resulting in large deviations which small effects normally negligible now have a noticeable effect because they run exactl
y in time with anything else. Resonance is the characteristic that greatly increases the quantity depending on certain frequencies at constant steering greatness. Another feature is that for a brief moment the structure echoes while the source has been removed. Resonance is a way to show the electron distribution with certain sound reverberation and emotional composite share the experience that can not be described with the aid of a Lewis structural formula.
