1. The problem statement, all variables and given/known data Determine the wavelength of light being used to create the interference pattern in 3 different ways from the given data. -The angle to the 8th maximum is 1.12° -The distance from the slits to the screen is 302 cm -The distance from the first minimum to the fifth minimum is 2.95 cm -The distance between the slits is 0.00025 m 2. Relevant equations Δx = λL/d sinθ= mλ/d sinθ= (n-1/2)λ/d xn/L=(n-1/2)λ/d xn/L=mλ/d 3. The attempt at a solution You know that 4Δx=2.95 so Δx=0.7375 subbing that in you get 0.7375=3.02λ/0.00025 and λ=611 nm next sin 1.12=8λ/0.00025 and λ= 611 nm my problem is with the last one. I have no idea how to find xn (the distance between a point on a nodal line and the right bisector) as it is not a given and we don't have any info about the right bisector. So I don't even know how to begin with this problem. Also, I also want to double check that minimum=nodal region and maximum=antinodal region. A simple fix if I'm wrong but just wanted to double check. Thanks in advance!
