Why Does a Green Glass Plate Absorb Everything Except Green?

AI Thread Summary
A pure green glass plate absorbs all wavelengths of light except for green, which is why it transmits that color when white light passes through it. The confusion arises from the comparison to absorption spectra observed with sodium vapor, where specific wavelengths are absorbed, resulting in dark lines. The green glass does not absorb green light because it is designed to transmit that specific wavelength. Thus, the statement in the book is correct; the glass absorbs everything except green. This principle highlights the selective absorption properties of colored glass in relation to white light.

Homework Statement


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"


Homework Equations




The Attempt at a Solution


I don't 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 that's 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

What color would you see at the end of where the white light passes through the glass ?
 
No, i can't understand your query. I assume green colour alone should be absorbed.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
