Hi guys, have a question about the experiment. If i work out the number of wavelengths hitting the screen, how do I determine whether the signal is maximum or minimum?
e.g if there are 6 wavelengths from slit one that fit in the distance to the screen, and 9 wavelengths from slit two, would this be a maximum signal?

I think it would not, as if the wavelength can reach 9 there would be a max where both wavelenghts were 9. However, I'm unsure how to phrase this/if it's right, so if anyone could help with any part I'd really appreciate :smile:

:smile:

Thanks!

Or, alternatively, would it be maximum as both hit at a full wavelength? so it would be constructive interference..?
