Old simulations

An old simulation illustrating how to determine the speed of sound in air using an oscilloscope, a low frequency generator, a loudspeaker, and two microphones. Developed by Farid Minawi, physics-zone.com. محاكاة قديمة توضح كيفية تحديد سرعة الصوت في الهواء باستخدام راسم الذبذبات ومولد التردد المنخفض ومكبر الصوت وميكروفونين. من إعداد فريد مناوي، موقع، physics-zone.com

These simulations were made using the Adobe Flash/AcrtionScript. You can download them and run then in Windows.

Stroboscope Simulation

Stroboscope Simulation

This is a new simulation of a rotating disk being illuminated by a stroboscope. You can control the speed of the disk and the frequency of the stroboscope, and see how the white spot on the disk appears. You can check all the cases of stationary appearance and the slow-motion appearance.
