I found it okay but I struggled with the boundary question where you had to measure with a rule to find the speed and refractive index.

Yes that was difficult as well. What did you do for the 6 marker?

So I think I put that the sources must be both of the same wavelength and monochromatic. Lasers are monochramitc but a filament bulb isn't. I also said that they should be in phase.

Not too bad. I think I messed up the refraction question a little (though hopefully it'll be alright when ecf marks are accounted, if they are). For the 6 marker I said the sources had to be coherent, of sufficient intensity to reach the screen, fully diffracted and not too far seperated. I don't know if any of that was right though.
