## Homework Statement

Light goes through two slits 40 mm apart. Does an angle exist at which light of wavelength 440nm has a maximum and light of wavelength 660nm has a minimum?

## Homework Equations

dsin[tex]\theta[/tex]=m[tex]\lambda[/tex]1 = maximum

dsin[tex]\theta[/tex]=(m+ 1/2)[tex]\lambda[/tex]2 = minimum

## The Attempt at a Solution

I solved for sin[tex]\theta[/tex] in each case, so I got:

m[tex]\lambda[/tex]1 = (m+ 1/2)[tex]\lambda[/tex]2

[tex]\lambda[/tex]1 = 660nm

[tex]\lambda[/tex]=440 nm

Now I'm stuck. Both Ms do not have to be the same, right? So do I have to solve for one of the Ms and stick it into an equation I listed in part 2 above? If so, that's a crazy calculation. Thanks!
