Document Summary
Atoms are super small and there are too many to account for. They are composed of protons (+) and electrons (-) in the nucleus with neutrons surrounding them. An ion is an atom with an unbalanced number of protons and electrons. A positive ion has more protons and a negative ion has more electrons. An isotope is an atom with an uneven number of neutrons that messes up the atomic number. The amplitude is how high the wave is from crest to the center of the wave. The frequency is how many waves pass a certain point per second(cid:224) 1/period. The wavelength is how long a wave is. Wave speed is wavelength / period or wavelength x frequency. A transverse wave travels at a right angle (up & down) A longitudinal wave travels in compressions toward the same direction (cid:224) ex. They then continue on unchanged by the interference. Coulomb"s law tells us the force (n) between two charges.
