Using concepts #13 #14 on the review sheet, mark the option that describes the type of spectra seen by the observers in the figure above. (Hint: Also use the Types of Spectra tutorial.) Group of answer choices Observer A sees emission lines, B sees absorption lines, C sees continuous, D sees emission lines + continuous. Observer A sees absorption lines, B sees emission lines, C sees continuous + emission lines, D sees emission lines + absorption lines. Observer A sees continuous + emission lines, B sees absorption lines, C sees emission lines, D sees emission lines + absorption lines. Observer A sees absorption lines, B sees emission lines, C sees continuous, D sees continuous + emission lines. Observer A sees continuous + emission lines, B sees emission lines, C sees continous, D sees absorption lines.
