## Homework Statement

Light of 650 nm is incident on two slits. A maximum is seen at an angle of 10.93degrees and a minimum of 11.73degrees. What is the order m of the maximum?

What is the distance d between the slits?

## Homework Equations

dsin(theta)=m(lambda) - max

dsin(theta)=(m+1/2)(lambda - min

## The Attempt at a Solution

So I started out with the two equations, one for the constructive interference and destructive interference. I solved one equation for d, and then substituted that solved equation into the other to try and find m. I don't know if it was an error in math or what, but I can't seem to solve this problem. Is there an easier way that this, or is this the easiest?

P.S. Sorry I've posted three threads for three different questions, but I'm having trouble with this chapter. Thank you for your patience and your help.
