Problem 5 For each part of the below question, choose one correct answer from the drop-down multiple-choice menu box. Two parallel narrow horizontal slits in an opaque vertical screen are separated center to center by \(d=\) 5 \(mm \). These are directly illuminated by a plane wave from a filtered discharge lamp. Horizontal fringes are formed on a vertical viewing screen 17 \(m \) from the aperture plane. The center of the sixth bright band is \(y=\) 19 \( mm ) above the center of the zeroth/central bright band. a) \( \lambda_0\)= b) If the entire space is filled with a medium of an index of refraction \(n=\) 1.376, where would the sixth fringe now appear (find (y \))? \(y\)= Determine the wavelength \( \lambda_0 \) of the light in air. 4
