Part-1: Use the single-slit attachment, and shine the laser on 1" single slit. Place a piece of paper a meter away from the slit and measure the distance between center of first dark fringe from center of central bright fringe. Repeat for multiple dark fringes both to the left and right, at least 3 total readings. Repeat the experiment for other single slits. Calculate the wavelength of laser using single-slit diffraction equation. Calculate average laser wavelength. (Make sure to convert your answer into nm. Compare your average wavelength value with actual value of 638 nm. lexperimental - actual %error actual • 100 Part-2: Now replace single-slit attachment with a human hair. Repeat the measurements. Now using wavelength calculated in part 1, calculate the width of the human hair. dz laug Part 2 a [Yi Y² 13 Y3 X 12 le 10.002 6 5 65 4 0004 3.5 2.52 5. 008 | 8 | 7 | 10.016608 to 8 7 7 7 7.5/5.5 76 1171767 14 1 19 Parr 16 4.5
