Homework Statement


Youngs double-slit experiment is performed with 589nm light and a distance of 2.00m between the slits and the screen. The tenth interference minimum is observed 7.26mm from the central maximum. Determine the spacing on the slits.

Homework Equations


Iavg = (Imax) cos^2 [(pi d sin angle) / lambda]
(it is very frustrating not being able to insert relevant symbols )

hm you seem to be using the wrong formula, in this case we are not measuring the intensity but using: distance from central max= (wavelength * distance to screen*order number)/spacing of slits. Hoped that helped
 
589nm x 2.00m x 10 / .00726m = spacing of slits

1622589m between slits?

Sorry to change the topic, but look here for some info on LaTeX https://www.physicsforums.com/showthread.php?t=8997 if you want to make the equations look right
