While dealing with continuous absorption spectrum, my book depicts like this
" A pure green glass plate when placed in the path of white light, absorbs everything except green and gives continuous absorption spectrum"
The Attempt at a Solution
I dont understand this, because i have studied when light from the carbon arc is made to pass through sodium vapour and then examined by a spectrometer, a continuous spectrum of carbon arc with two dark lines in the yellow region is obtained.
So, since sodium vapour emit wavelength of 5896 Armstrong 5890 Armstrong, yellow lines of carbon arc spectrum are absorbed and those lines are absent in the absorption spectrum.
If thats the case then the statement in my problem statement sounds wrong. A pure green glass plate should absorb green colour present in white light. But it is given, everything is absorbed except green.
Am i interpreting wrong or the book is wrong? Please help members
