Wave Interference Simulator vs HYOURAKU

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.

HYOURAKU is a visual education app for learning the science of Earth's ice by watching and moving beautiful simulations. It covers the basics of glaciology, sea ice and paleoclimate in eight topics, from high-school earth science up to introductory glaciology and climatology. [Eight modes] - Glacier Dynamics See how a glacier flows even though it is solid, drawn as a valley cross-section. The temperature and accumulation (snowfall) sliders shift the equilibrium-line altitude (ELA), and the ratio of accumulation to ablation zones sets the mass balance. A positive balance advances the terminus; a negative one makes it retreat. - Ice-Albedo Feedback White sea ice reflects most sunlight, while the dark ocean absorbs it. Experience the positive feedback "less ice, lower albedo, more absorbed heat, even less ice". Push the forcing past a threshold and the ice collapses abruptly (tipping), and restoring the forcing does not easily bring it back (hysteresis). - Ice Core and Paleoclimate Each layer of an ice core traps the air of its time as bubbles. Drag the core up and down to travel into the past and read the CO₂ in the bubbles and the temperature reconstructed from isotopes, across hundreds of thousands of years paced by Milankovitch cycles. - Permafrost As it warms, the active layer deepens and thawing permafrost releases CO₂ and methane through microbes: a carbon feedback that drives further warming, shown in a soil cross-section. - Snow Crystals A snow crystal's shape is set by the cloud's temperature and supersaturation. Following Ukichiro Nakaya's diagram, plates, columns, needles and dendrites are drawn with six-fold symmetry. - Sea Level Rise Melt sliders for Greenland, Antarctica and mountain glaciers raise the sea and flood a coastal city in cross-section. A zoomed tide gauge shows how much the sea has risen. - Sea Ice (new) Arctic sea ice grows in winter (largest around March) and shrinks in summer (smallest around September). Follow the seasons month by month and see how warming cuts the summer minimum faster than the winter maximum, until the Arctic becomes ice-free in summer. - Avalanche (new) From the slope angle, new snow depth and weak-layer strength, the app compares the shear stress on the weak layer with its strength. When stability drops below 1, a slab breaks away and slides down. Find out why avalanches are most common on 30–45° slopes.
