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
im not really understanding because if i solve for t when m=0 if i plug it back in and solve for m im just going to get 0
You're missing my point. The values of m: 0, 1, 2, 3, 4... If the maximum value of m = 4 (pretend), then how many values of m are there?
