Instructions for the lab are here:

• Instruction (*.pdf)

I suggest that you download it to your iPad to refer to. Download and open it in Notability and you can write notes on the pdf.

What to hand in

Hand in an Excel spreadsheet which includes:

• The data and a graph from your scan of the pattern with both slits open.
• The data and a graph from your scan of the pattern with just a single slit open.
• Your responses and calculations for that "One last calculation to do..." section.
