Touch Waves vs Galaxies

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. List of animations: Motion of harmonic oscillator, Motion of damped oscillator, Motion of driven oscillator, Progressive transversal wave, Reflection and transmission on string, Standing waves on string, Progressive longitudinal wave, Beating wave, Acoustic frequency, Acoustic Spectrometer, Acoustic Doppler effect, Snell-Descartes’ law, Law of spherical interface, Law of thin lens, Law of thick lens, Law of spherical mirror, Geometric aberration, Chromatic aberration, Visible spectrum, Electromagnetic wave in 3D, Electromagnetic spectrum, Absorption and emission of photon, Types of polarization, Types of polarization in 3D, Fresnel’s coefficients, Reflection and transmission in 3D, Degree of polarization in reflection, Interference in 3D, Young's interferometer, Michelson's interferometer, Fabry-Pérot interferometer, Diffraction by rectangular aperture, Diffraction by circular aperture.

Galaxies! The most mysterious structures in the universe! Magnificent formations that seem the largest and most inaccessible. They are so far away that they can hardly be seen even with our telescopes. But we have put together images taken by the magnificent telescopes at ESO for you. FEATURES • In the "Browse" section, you will be able to quickly browse through hundreds of photos and also read detailed information about them. • In the "SlideShow" section, you will be able to browse through hundreds of impressive photos in full-screen size and feel as if you were in there at that moment. If you wish, you will be able to get detailed information about these impressive sights by tapping the Info button. Additionally, you can start auto-play by tapping the Play button on the top right. • In the "Gallery" section, you will be able to see all the photos impressively, show what you want in full screen, and when you want to examine them in detail, you can zoom in with the help of your fingers. • For those who do not want to be contented with just beautiful photos, there are many videos in the "Videos" section. • You will get detailed information about the ESO.
