Name: Lab: 2-Point Interference 25 Purpose: To test the equations for 2-Point Interference. Procedure: 1. Click on the link to load the pHet Wave Interference Simulator 2. Click on "Slits" 3. Under the "Amplitude" slide bar, change it from water waves to sound waves. 4. Change it from "One Slit" to "Two Slits" 5. Drag the slits as far to the left as possible 6. Drag the "frequency" to the highest setting 7. Make the "slit width" as small as possible 8. Make the "slit separation" as large as possible 9. Click the green button on the sound wave generator to start making waves 10. Use the "Measuring Tape" to measure 'd' 11. Treat the right-most side of the simulation the 'screen'. Measure 'L' Observations and Analysis d = L = [2 marks] Part A: Using |PS,-PS,|=ml to find > [6 marks] Locate the two 1" order maxima - one is above the middle maximum and one is below Use the measuring tape to measure the length of the line segments Use the appropriate formula to calculate ^ using your measurements m PS, PS2 PS,-PS2 A 1 (upward) 1 (downward) Calculations:Part D: Calculate A using a= dAx L [3 marks] . Explain how you measure Ax . Measure Ax and use it to calculate A AX = Calculations
