As we have seenin the previous section,the terms with + signs result in waves traveling in the negativex , y, or z direction, while the terms with - signs result in wavestraveling in the positive direction. Both solutions are possible and are valid; the amount to which these various terms are excited is dependenton the sourceof the fields.
