Document Summary

Model that explains the strange behavior of the electrons. Type of energy embodied in oscillating electric and magnetic fields: magnetic field. Region of space where a magnetic particle experiences a force: electric field. Region of space where an electrically charged particle experiences a force: amplitude. Determines color: wavelength (, frequency (, =(cid:1855) (c = speed of light; = wavelength) same distance units, nano = (cid:883)(cid:882) (cid:2877) The number of cycles (waves) that pass through a stationary point in a: electromagnetic spectrum. Does not carry enough energy to damage biological molecules. If two waves of equal amplitude are in phase when they interact that is, they align with overlapping crests a wave with twice the amplitude results: destructive interference. Two waves are completely out of phase when they interact that is, they align so that the crest from one overlaps with the trough of another the waves cancel: diffraction.
