answr vs LabOptique

// answr answr is a curiosity device. ask anything about the world around you. get clear answers that explain the why behind things—not lectures. like a smart friend who makes you see things differently. // how it works you ask a question. we strip away any identifying information, route it through a secure server (cloudflare) to an ai (openai's gpt-5-mini), and return your answer. that's it—no conversation history, no profile building. each question stands alone. // daily curiosities three fascinating questions arrive each day at noon. why is the sky blue at noon but red at sunset? how do fireflies sync their flashing? what makes bread smell so good when it's baking? these aren't trivia—they're doorways to understanding. // honest about what we know every answer is rooted in evidence. when science doesn't have an answer yet, we say so—the boundaries of knowledge are themselves fascinating. and since answr uses ai, answers might sometimes be wrong. for health, legal, or financial decisions, always verify with an expert. // why it's private we can't track you because we don't know who you are. no account, no user id, no device id—just an anonymous question that arrives, gets answered, and vanishes. • questions route through cloudflare, never directly to openai • openai is told not to store anything • your history lives only on your device there's nothing to forget because there's nothing to remember. your curiosity is yours alone. // explore more good answers open doors. each response offers paths to go deeper, broader, or somewhere unexpected. — answr: to be interesting, be interested. terms of use: https://getanswr.com/terms privacy policy: https://getanswr.com/privacy

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.
