This app invites you to explore the relative motions of our solar system's planets, their moons, and several exoplanet systems. It is based on ideas presented in "A Little Book of Coincidence" by John Martineau. Are the amazing patterns created by these orbiting bodies just a coincidence, or is something more than that going on? Take a look and see what you think. Be sure to check out the special relationship between the Earth and Venus.
LabOptique

Examine various aspects of geometric and wave optics: - Geometric optics: thin lenses, the concept of approximate stigmatism, depth of field, vision of the eye (accommodation, etc.). Possibility of combining multiple lenses, an eye... - Wave optics: from the concept of path difference (for senior year students) to the effects of a glass plate, the concept of coherence length..., in various situations: infinitely narrow or wide Young’s slits or holes, freely movable sources to recreate a Michelson interferometer, a diffraction grating, a Lloyd mirror, using either a monochromatic source or white light.
