Question 1 (2.5 points) aI: Light from a He-Ne laser (633 nm) passes through a narrow slit and is seen on a screen 1.57 m behind the slit. The first minimum (dark fringe) in the diffraction pattern is 0.720 cm from the central maximum. How wide is the slit? Report your answer in millimeters. Your Answer: :] Answer Question 2 (2.5 points) E-Il Interference patterns occur when wavefronts meet from nearby slits, and add (or cancel) out the intensity of each other. Question 3 (2.5 points) 5- A double slit interference pattern is observed on a screen 0.92 m behind two slits spaced 0.30 mm apart. 2 bright fringes span a distance of 0.89 cm (measured from center to center, and you are measuring from the 2th fringe on the right to the central bright fringe). What is the wavelength of the light? Record your answer in nanometers. Your Answer: :) Answer Question 4 (2.5 points) E-Il Constructive interference between wavefronts from two adjacent slits will result in a dark part of the pattern
