It’s hard to say without seeing your setup, and this one in particular is a difficult one to image/video since it’s a light experiment. Let me send you a private email with a suggestion in it.
Hi,
we got a piece of diffraction grating that says 13,500 lines per inch and tried to make the calibrated spectrometer but couldn’t see lines on the ruler, so we were wondering if we got the wrong diffraction grating?
No, you can choose any one that you’d prefer. The tend to be expensive, so look for “rainbow” glasses or use an old CD.
We don’t normally link to Amazon for that reason – the links change so quickly! I put it linked to a category, not a particular item.
the diffraction grating link doesn’t connect with a purchasable item any more. i’m looking on amazon – some say “double axis,” some say “linear,” there are different lines/in… does it matter?
