complete the tables

Procedure: 1. Set up the laser at one end of the optics bench and place Single Slir Disk in 1ts holder about 3 cm 1n front of the laser. Attach the mm scale to the screen and set the screen up at the other end of the bench. b Turn the laser on and select the 0.08 mm slit by rotating the slit disk until the 0.08 mm slit 15 centered in the slit holder. Adjust the position of the laser beam from left-to-right and up-to-down until beam is centered on the slit. 3. Measure the distance from the slit to the screen (L) 4. Turn off the room lights and measure the positions of the first and second minima in the diffraction pattern (v1 and v2) LA Fepeat the same steps for 0.04 mm and 0.02 mm slits. f. Fill out the Data Table and calculate 2 of red light for all six measurements. Calculate the average A and % error. (Standard value for red light 15 A = 690 am) Data Tables First Minimum (p =1) SlitWidth(m) | L(@m | Yim | A@m | 0.08x103 0.0031 ] 0.04x10* \" 0.0141 ] 0025100 [ 008 | 0.0050 ] Second Minimum (p =2) + Slit Width (m) 0.08x10 Joos Jol4s | 0000000 | 0.04x10 008 [ 0.0311 ] 0.02x10 ]0.08 [0.0072 ] Wavelength of Light Purpose: Experimentally determine the wavelength of the red light from a diode laser. List of Materials: Optics Bench and Screen, Diode Laser (OS-8525), Single Slit Disk, millimeter scale to cover the screen, and meter stick. Theory: When a beam of light passes through a narrow opening, or slit, there is spreading of light and interference, which is called diffraction. The angle to the minima (dark spots) in the diffraction pattern is given by formula, a sinOp = p2 (p = 1,2,3....) where a - the slit width (m) 0 - angle from the center of the pattern to the ph minima (1 for the first minimum, 2 for the second minimum_ counting from the center out) 2. - the wavelength of the light (m) Since the angles are usually small, it can be assumed that sine ~tane From trigonometry tan 0 = y/L where y - the distance on the screen from the center of the pattern to the pit minimum L - the distance from the slit to the screen Finally 2 = a y /PL
