1. Blue light of wavelength 445 nm passes through a slit of width a = 0.319 mm wide. The diffraction pattern is seen on a screen 4.00 m away. NOTE: 445 nm = 4.45x107 m. ALSO NOTE: 0.310 mm = 0.319x103 m. What is the width of the central bright fringe? (a) (b) What is the width of the second bright fringe on either side of the central one. Hint: Get the distance between two adjacent dark spots, which you can see on the image below. The locations of the dark spots are given by the formula for single slit diffraction and the minima, which mark the dark spots. For example, the first fringe is the central fringe, and the second fringe is adjacent to the central fringe. The second fringe is between the first and second dark spots, which are given by the formula in the lecture notes or book. त्रै k axis
