Touch Waves8.3

Touch Waves is an educational application helpful for a high-school or university course of wave physics.
It contains not only a memorandum of the basic equations, but it also contains approximately thirty animations (some in 3D) illustrating the various concepts of wave physics.

More than 70 screens of wave physics!

For teachers !! Connect your iPad to a video projector and show the animations to your students in classroom.
List of covered subjects:

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 formulation of polarization,
reflection and transmission, interference, diffraction, Doppler-Fizeau effect.

Each section contains at least one animation.
