Waves from two sources vibrating at the same frequency will meet up with one another to produce an interference pattern consisting of nodes and antinodes. This can be (not so easily demonstrated with a ripple tank set up or (more easily) with our Ripple Tank Simulator.

Users are encouraged to open the Interactive and explore. We do not have a student activity sheet for this simulation. We recommend that you make your observations and then navigate to our Two-Point Source Interference Patterns Interactive to continue your learning.

Learners and Instructors may also be interested in viewing the accompanying Notes page. Technical information, teaching suggestions, and related resources that complement this Interactive are provided on the Notes page. View Notes.
