About this Simulation

This simulation models the interference pattern created when two waves of slightly different frequencies overlap in time. Learners adjust individual wave frequencies and observe how beat phenomena emerge, visualizing the periodic variation in amplitude caused by constructive and destructive interference.

Learning objectives: Understand how superposition of waves with different frequencies produces beats | Relate beat frequency to the difference between individual wave frequencies | Visualize the relationship between time-domain waveforms and frequency-domain interference patterns
