Huygens3D
The digital ripple tank
$3.99
Huygens3D brings the exploration of fundamental wave phenomena to iPad and iPhone, making it a full alternative to the classic ripple tank in physics lessons.
Interference, diffraction, reflection and refraction are simulated just like in a real water tank. Thanks to the intuitive controls, every experiment is set up in seconds, so all students can experiment on their own.
Features:
• various wave sources (point, line, points on a line, circle), as a continuous wave or a wave packet
• various obstacles, slits, prisms and lenses
• rain field for random waves
• pause and step-by-step mode
• phase probes with an oscilloscope view showing the phase difference
• tape measure for measuring in length units and in multiples of the wavelength
• screen showing interference and diffraction patterns
• share experiment setups via AirDrop, Messages or Mail
