Walking NY vs Wave Interference Simulator

The Walking New York App will show you old photographs of wherever you are standing in Brooklyn or Queens. It locates the block you are on and selects old photos of buildings on that site or nearby. Created by the La Guardia and Wagner Archives, La Guardia Community College, CUNY, the app features selections from the New York City Housing Authority Photograph Collection (housed at the La Guardia and Wagner Archives), Queens Public Library, and Brooklyn Historical Society’s Photograph Collection. Users can also browse the map to find all of our provided locations, as well as share photos from their locations to Facebook and Twitter. Currently supporting the boroughs of Brooklyn and Queens, we will be adding Manhattan, the Bronx, and Staten Island, so users can find themselves fully “Walking New York.”

The perfect app for high school physics education, offering real-time, visual simulations of wave interference and reflection. 【Key Features】 Intuitively control and observe complex phenomena like wave interference (interference fringes, antinodes, nodes) and reflection (fixed and free ends)—concepts that are often hard to grasp through textbooks alone—right on your smartphone or tablet. Spherical & Plane Wave Placement: Freely position up to two wave sources, with fully customizable wavelengths, frequencies, and phase inversions. Reflection Wall Simulation: Place a reflecting wall (fixed or free end) to visualize reflected waves, virtual wave sources, and even what happens behind the wall in real-time. Interference Line Display: Highlight antinodal lines, nodal lines, and moving interference points to logically understand the mechanics behind wave interference. Total Control: Supports fast-forward, rewind, and frame-by-frame playback. Zoom in and out with a simple pinch, and use smooth scrolling to observe every detail. Classroom & Projector Ready: Includes a "Bold Display" mode for clear screen projection, along with slow-motion and frame-by-frame playback features. 【Recommended For】 - Anyone who wants to appreciate the visual beauty of physics phenomena. - High school and college prep students looking for hands-on understanding of wave superposition and interference. - Teachers seeking interactive, visual educational tools for their classrooms.
