Interference of Waves Simulation

ByFarid Minawi

This interactive wave interference simulation demonstrates the fundamental principles of wave superposition using two sources. Users can adjust key parameters including wavelength, amplitude, phase difference, and source separation to observe how waves interact and produce complex interference patterns. The simulation features a real-time probe tool that displays individual wave amplitudes and their resultant superposition, showing constructive and destructive interference at different points in the field. The visual representation includes radiating wave fronts from both sources, with characteristic alternating bands of high and low amplitude clearly visible throughout the interference pattern.

Phase Difference Between Sound Waves Simulation

A fix to the “Phase Difference Between Sound Waves Simulation”

ByFarid Minawi

In response to valuable feedback about the simulation “Phase Difference Between Sound Waves Simulation,” highlighting the slight inaccuracy of the obtained speed of sound of air, which was found to be about 349 m/s, this inaccuracy was fixed, so now it gives 346 m/s as it is supposed to give at room temperature.

Projectile Game

ByFarid Minawi

In this game, you must employ the projectile equations to win.
The game consists of three levels, each of which must be completed by scoring at least 8 out of a possible 10 tries. In the first level, you must hit a ground target that shifts position after each attempt. In the second level, you will need to alter the ball’s trajectory to pass over a wall. In the third level, the target flies and changes position both horizontally and vertically in each trial.

Phase Difference Between Sound Waves Simulation

ByFarid Minawi

With this rich simulation, you can visualize and measure the phase difference between two sound waves using two microphones connected to an oscilloscope. Moreover, you can determine the speed of sound in air by measuring the distance between the two microphones when their waveforms are in phase, taking into account the frequency of the sound wave that is controlled by the sine wave generator.
