Physics Notes 2/5 by Jess

Diffraction- wavelength vs sive of opening
small opening-more diffraction
large-less diffraction

Resonance- increased amplitude of oscillation of a mechanical system when subjected to vibration at or near its own natural frequency

(insert Julia's "Oh, S***!" here)

Natural Frequency- frequency at which objects tend to ocillate when disturbed
-if objects are excited at natural fequecny, the aplitude of vibration will increase
-Electrical circuits also exert electricity
Example: pushing a swing, or musical instrument

I think we covered more then just that I hope you added more to clear up any loss ends or maybe add some pitures
