Interference of Waves Simulation
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.

Education before technology
Educational technology is more about strategically leveraging technology to enhance, transform, and even redefine teaching and learning than just merging education with technology. You have to be a strong educator equipped with learning theories, educational methodologies, and statistical analysis in the first place to be a successful educational technologist.

Refraction of Light Simulation
With this simulation, you can experiment the refraction of light between air and a transparent semi-disk. You can choose the material of the disk from a list of materials. Also, you can determine the index of refraction of the semi-disk when you apply Snell’s law to measurements you take in the simulation.

An inspiring code
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.

Simplicity is power
In creating interactive educational tools, simplicity is power. A minimalist design doesn’t just look clean; it helps learners focus on what truly matters. Instead of overwhelming the user with unnecessary details, focus on providing a clear, interactive interface that mirrors the real-world experience.

Conservation of linear momentum
If this experiment is done in a situation where the net external force is zero on the loaded cannon just before and just after firing (like when the weight of the cannon is balanced with the normal reaction of the ground), then, when we calculate the product of the mass of the bullet by its velocity and the product of the mass of the cannon by its velocity just before and just after firing, we will find that before firing both were at rest so the product is zero for both, while, after firing, the two products are of the same magnitude but the velocities of the cannon and the bullet are of opposite directions.
