Class sets of diffraction gratings

[Jonathan Jaffrey]

Hi,

I'm keen to increase the number of Year 13 (or Y12!) class practicals done
with gratings.

I'm offering class sets of gratings with a free CD of worksheets &
PowerPoints of basic theory & experiments as follows:

 

20 off (10x1000line/mm plus 10x500line/mm) for $80 plus freight,

40 off (20x1000line/mm plus 20x500line/mm) for $140.

Good quality replica gratings protected by wipe clean plastic in 35mm slides
to fit standard rayboxes.

 

Order from: jjaffrey at slingshot.co.nz
