(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Light of wavelength 525 nm is used to illuminate normally two glass plates 26 cm in length that touch at one end and are separated at the other end by a wire of radius 0.03 mm. How many bright fringes appear along the total length of the plates?

2. Relevant equations

2*t=(m+1/2)*wavelength

3. The attempt at a solution

I thought t would be .6 since that would be the diameter. Then I solved for m and got 228. However webassign doesn't like this answer and im not really sure how to go about this problem
