electromagnetic waves - - light is the only thing we can see * originates from the accelerated motion of electrons * electromagnetic phenomenon - electromagnetic wave: made up of vibrating electric and magnetic fields if an electron vibrates up and down 1000 times each second, it generates an electromagnetic wave w/ a - frequency of 1000 Hz electromagnetic spectrum - - classification of electromagnetic eaves according to frequency - lowest frequency of visible light we can see appears ...

Light travels at.. - 3.00E+8 m/s Refraction is.... - the bending of light as it passes from one medium to another Reflectance - the ratio of the intensity of the reflected light Most of the waves in the electromagnetic spectrum are - invisible From low n to high n - a transmitted ray is bent, or refracted, toward the normal From high n to low n - a transmitted ray is bent, or refracted, away from the normal Light travels from one place to another along a path of least - time ...

Circuits - any path along which electrons can flow from the negative terminal to the positive terminal is Series Circuit - forms a single pathway for electron flow between the terminals of the battery, generator, or wall outlet Parallel Circuit - forms branches, each of which is a separate path for the flow of electrons Series Characteristics - -electric current through a single pathway -total resistance to current is the sum of individual resistances -current is equal to the voltage ...
