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.

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.

Virtual Oscilloscope is Now Mobile-Friendly!

Virtual Oscilloscope

This time I have updated Virtual Oscilloscope so it is now mobile-friendly. Long-press any button, knob, or slider and it will scale up to become comfortable enough for your touch so you can control it comfortably using your mobile device.
I also optimized the code to perform smoothly on mobile devices.
