1. The statement, all variables and given/known data
Hi I'm doing this experiment where we need to find the wavelength of our laser light source. I am unsure what the variables IV and DV would be and the controlled variables? Also how will I make the graph? I'm in AS level so please don't make it too solid for me thanks.
so we are to use: w=λD/s where w= fringe spacing D is distance from slit to screen and s is the slit seperation
in the form λ=ws/D
I think the controlled variables are the slit separation, s, the distance, D, but I am really unsure on the others.
