Can someone give about 20 easy examples of resonance?
acoustic resonances of musical instruments and human vocal cords the timekeeping mechanisms of all modern clocks and watches: the balance wheel in a mechanical watch and the quartz crystal in a quartz watch the tidal resonance of the Bay of Fundy orbital resonance as exemplified by some moons of the solar system’s gas giants the resonance of the basilar membrane in the cochlea of the ear, which enables people to distinguish different frequencies or tones in the sounds they hear. AM radios use resonant coil pickups on ferrite rods as compact aerials (much smaller than the wavelength) electrical resonance of tuned circuits in radios and TVs that allow individual stations to be picked up creation of coherent light by optical resonance in a “laser” cavity the shattering of a crystal wineglass when exposed to a musical tone of the right pitch (its resonance frequency). http://en.wikipedia.
