Homework Statement
I've conducted two laser experiments. One with single slit, and one with a double slit.
I've produced two graphs which look something like these;

Would anyone know how to go about roughly estimating how many wavelengths wide the laser beam used is?
Possibly from the graphs? (or maybe from other data)
Thank you.
