Lab: 2-Point Interference 25 Purpose: To test the equations for 2-Point Interference. Procedure: 1. Click on the link to load the plet 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 using this arrow. 6. Drag the "frequency" to the highest setting (max). 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 It should look like this: 50 cm 1 ms = 103 s Sound Generator Normal O Slow 372.0 cm 10. Use the "Measuring Tape" to measure 'd' . Drag it to use it. 11. Treat the right-most side of the simulation the 'screen'. Measure 'L' (distance from the centre of the slits to the screen centre).Name: :| . E l . d = L: [2 marks] Part A: Using IP51 PSEI = ml to find A [6 marks] o Locate the two 1\" order maxima one is above the middle maximum and one is below In Use the measuring tape to measure the length of the line segments o Use the appropriate formula to calculate A using your measurements.
