hi I just had a question, when you said that there are 300 lines (slits) per mm wouldnt that mean that there are only 299 gaps, so wouldnt you have to divide by 299 and not 300?
No it is 300. Ill put it in a more a visable concept. 5 lines per m So start Line at 0m Gap Line at 20cm Gap Line at 40cm Gap Line at 60cm gap Line at 80cm gap ------- Start again The gaps are line to line. if you had 300 lines per mm. You start with one line at the 0 mark and one at every (1/300 of a mm) with the last line at (299/300 of mm) with one more gap after. Hope that helps a little more visually Thanks for watching!
THANK YOU SOOO MUCH

thank you helped alot
Hi, i was just wondering why they say there is 300 lines per mm. Is 300 random or does it mean something because why couldnt it be 200 or 400 etc?
It is an estimation of the lines that are in the diffraction grating. It could be 200 or 400 but that would be a different grating entirely
