Hi All,
Noticed a CD spectrum on the ceiling this arvo.
I thought I would look for resolution by using a slit
-no luck.
Anyway, specifications:
Grating -Guide 8 CD
Slit -Boat modellers mini plane; width ~2.5mm
Slit to image -5m
Don't give teachers holidays -they go stir-crazy.
Merry Christmas to all Spectroscopists
