Homework Help: une lab de physics

Posted by URGENT on Tuesday, December 11, 2007 at 8:33pm.

Hello, we are doing a lab dealing with diffraction gratings. The problem I have is that we are supposed to find the number of slits, N, based on gathered information. I have x, L, d, m, and w, just not N, which is what I am trying to find. I also have the wavelength. Is this the right equation to use? dsintheta= mlambda and then reagrrange to find N, for d=(w/N) and sintheta= (x/L) so the equation for N would be to take mlambda and divide that by (x/L) which would be equal to w/n and then to find N you would divide out the w, but my answer won't work, it is way too small. Any ideas?
