Touch Waves 7.6

Touch Waves is an educational application designed to support high school and university courses in wave physics. It offers a comprehensive resource that includes a concise summary of fundamental equations alongside approximately thirty animations, some in three dimensions, which effectively illustrate key concepts within the field.

With over 70 screens dedicated to wave physics topics, the application serves as an extensive visual aid. For educators, it facilitates classroom instruction—by connecting an iPad to a video projector, instructors can display animations directly to enhance student understanding.

The curriculum covered encompasses:

• Vibration: Harmonic oscillator, damped oscillator, driven oscillator
• Wave on strings: Introduction, reflection and transmission, standing waves
• Acoustics: Introduction, reflection and transmission, Doppler effect
• Optics: Geometric optics, wave optics, polarization, Jones calculus of polarization, reflection and transmission, interference, diffraction, Doppler-Fizeau effect

Each section is supplemented with at least one animation for practical visualization.

The list of animations includes:

• Motion of harmonic oscillator
• Motion of damped oscillator
• Motion of driven oscillator
• Progressive transversal wave
• Reflection and transmission on string
• Standing waves on string
