Add a second source to create an interference pattern. Put up a barrier to explore single-slit diffraction and double-slit interference. Experiment with diffraction through elliptical, rectangular, or irregular apertures. Part 1. Wave Interference Simulation Activity 1. Experiment with the settings and choose the view that you prefer ('Top View' or 'Side View'.) Try checking the 'Graph' box and watch how the plot is related to the amplitude of the wave. 2. Set the frequency to the minimum. Use the 'Timer' to measure how long it takes for the wave to travel the length of the box. Click here to enter text. 3. Set the frequency to the maximum. Use the 'Timer' to measure how long it takes for the wave to travel the length of the box. Click here to enter text. Observing Sound Waves Now switch to observing sound waves (press the speaker icon). 4. Observe the motion of an individual particle (choose a random red dot). What can you say about its motion as the waves pass by? Click here to enter text. 5. What are the particles doing when no sound pulse is traveling through? Click here to enter text. . Q 6. What makes it realistic? I Click here to enter text. V
