Atom model. Atoms are made up of three particles: protons, electrons, and neutrons. Electrons are the smallest and lightest of the the three particles and they have a negative charge. The protons are much heavier and larger than electrons.
A resonator is a device or system that exhibits resonance or resonant behavior, that is, it naturally oscillates at some frequencies, called its resonant frequencies, with greater amplitude than at others.esonators are used to either generate waves of specific frequencies or to select specific frequencies from a signal. Musical instruments use acoustic resonators that produce sound waves of specific tones.
A suppressor (or a silencer) is a device that is screwed on to the barrel of a gun and designed to reduce the amount of noise and flash generated by a weapon. Before we start to study about these devices, it is good to clear up a few myths about them (and these myths are mainly due to Hollywood movies).
