Prism Lab vs Studizy

Prism Lab is an optics bench in your pocket. Put a piece of glass on the graph paper, aim the laser at it, and watch the light bend, bounce and split, with every angle measured for you. It follows the experiments from a school ray box kit, so it works as a companion to the lab or on its own. THE BENCH • Nine pieces: a simple surface, 45-90-45 and 60-60-60 prisms, rectangle, square, semicircle, convex and concave lenses, and an optical fibre. • Drag the laser and where it aims. The angles of incidence, refraction and reflection update as you move. • Tap any angle and type the value you want. The laser swings there so you can see how it gets to it. • One, three or five parallel beams, to find the focus of a lens. MATERIALS • 119 materials for the piece and for what surrounds it: glasses, liquids, gems and gases, each with its refractive index. • The critical angle is worked out for every pair, and you can see total internal reflection happen. COLOUR • White light opens into a spectrum, because each colour bends by its own amount. • 77 materials use published dispersion data. For the rest the app tells you the spread is an estimate. • Red, yellow, green, blue and violet lasers, in the width you choose. LIGHTS OFF • Turn the lights off and the beams glow, as in a dark classroom. NO STRINGS • No account, no ads, and no data collected. • Everything is free. If you find it useful you can buy the developers a coffee. In English, Spanish and French, for iPhone and iPad.

Your course, as an interactive sheet. Drop in a PDF, some slides or a photo of your notes. Studizy turns it into a sheet: the course rewritten section by section, with the diagrams your notes were missing - not an automatic summary spat out in three paragraphs. ONE SHEET. AND EVERYTHING IT OPENS. Structured sheets The course reorganised, chapter by chapter, with the diagrams your notes were missing. Quizzes Questions drawn from your own sheet. You revise what you uploaded, not an average syllabus. Audio summaries Every section read aloud. Revise on the bus, walking, at the gym. Duels Take on a friend with the questions from your sheet. The same course, as a competition. EVERYTHING STAYS FILED Your sheets stack up in a library, sorted into folders and findable by search. Share a sheet by link, or export it as a PDF to print. IN YOUR COURSE'S LANGUAGE An English course gives you an English sheet, read by an English voice. The same goes for French, Spanish, German, Italian and Dutch. WHAT YOU NEED A course. A PDF, slides, a photo of your handwritten notes, or pasted text. Studizy is free to start, with no card required. Sheets, quizzes and audio use credits; a subscription or a credit pack adds more.
