Over 2,000 people visited Virtual Oscilloscope in mere 7 days

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

In this game, you must deploy 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.

Fixes to the Stroboscope Experiment simulation

Stroboscope Simulation

Since the frequency of the slow apparent motion in the stroboscope experiment varies depending on various factors that are not taken into consideration in the simulation, an essential change has been made to the code of the Stroboscope Experiment simulation to address the frequency of this apparent motion in the observation remarks.

A New Publication Based on The Virtual Oscilloscope Simulation

The paper: Using a web-based and stand-alone oscilloscope for physics experiment during Covid-19 pandemic, Mahizah Ismail et al (2023),  Phys. Educ. 58 015006, is based on the Virtual Oscilloscope simulation. This paper was authored by Mahizah Ismail, Farid Minawi, Wan Zul Adli Wan Mokhtar, Noraihan L Abdul Rashid and Ahmad K Ariffin.

Area Model of Partial Products

Area model of partial products

Elementary math teachers know the importance of this model in teaching the concept of applying distributive property in area model.
The idea is to break one large area (which represents the product of two numbers) into several pieces (products of smaller numbers), then to find the areas of the pieces individually, and finally add to get the area of the whole (the product of the given numbers).

Long Division Simulation – Float

Long division with floating point

If you or your student or child are having difficulties in learning long division, then you will find this simulation comprehensive and instructional, that guides the learner through the process step by step. This application is for long division with float quotient. Another application on long division with remainder is also available in the simulations section.

Phase Difference Between Sound Waves Simulation

Phase Difference Between Sound Waves Simulation

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.
