Designed to replicate the functionality of a real oscilloscope, the Virtual Oscilloscope has captivated the attention of students, educators, and electronics enthusiasts alike. Its intuitive interface and accurate waveform representations have garnered positive feedback, making it an invaluable resource for anyone interested in circuit analysis and electronic waveforms. I extend my gratitude to all those who have supported me and invite others to join this immersive learning experience.

Projectile Game

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.

These lines portray a tale of creation and vanishing. It describes the creation of a photon, its subsequent disappearance when an electron absorbs it on the cathode plate’s surface, the subsequent departure of the electron from the cathode, and lastly the eventual disappearance of the electron when it reaches the other plate and captured.

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.

Photoelectric Effect Experiment Simulation

ByFarid Minawi

With this comprehensive and realistic-like photoelectric effect experiment simulation, you will be able to illustrate the following:
The variations of the photocurrent versus potential.
The variations of the photocurrent versus light intensity.
The variation of the kinetic energy of the ejected electrons versus the incident light frequency.
It comes with a graph where you can trace each type of variation as you vary the parameters of the experiment.
Plus, you can experiment and discover more with this simulation.

Charging by Induction Simulation

ByFarid Minawi

Using this simulation, you can experience the phenomenon of charging a metallic ball by induction in the first stage and charging the ball by contact in the second stage after the charged rod touches the ball. The displayed charges are for an illustrational purpose, and they are not seen in reality. You can disable the display of charges on the rod and on the ball.
In this simulation, you can try two situations, one in which the rod is positively charged and another in which the rod is negatively charged, and you will see that the two situations result in the same observation.
