Q

discuss the electrochemical effects

A

application of faraday’s law - chem reax is proportional to the amount electricity passing

kaya the polarity from residual charge forms chemical compounds

Q

compare the electrochem effect of symm and assym waves

A

symm - no residual charge; no effect

assym - depends; AAA or CAB
