Every day is an experiment!<\/strong><\/span><\/p>\n<p>Our world is absolutely flooded with waves\u2014sound, light, earthquakes, and even the signals for your smartphone. However, it is a well-known fact that many students find physics suddenly difficult when they transition from studying mechanics to the world of waves.<\/p>\n<p>This happens because you have to completely flip your perspective. You have to move away from the idea of an object physically traveling to a new location and instead embrace the concept that <b>only the vibration (energy) is moving forward<\/b>, while the material itself stays put.<\/p>\n<p>Today, I want to introduce some exhibits from the National Museum of Nature and Science and my own digital teaching tools that will help you intuitively grasp this world of waves. First, let\u2019s observe the dynamic movement of actual waves.<\/p>\n<p><iframe loading=\"lazy\" title=\"\u5b9f\u969b\u306e\u6ce2\u306e\u89b3\u5bdf\uff08\u56fd\u7acb\u79d1\u5b66\u535a\u7269\u9928\uff09\" width=\"1140\" height=\"641\" src=\"https:\/\/www.youtube.com\/embed\/hvcGUJmmVxY?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<h3>The Secret of Transverse Waves: Dancing Bees<\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-32423 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2018\/12\/35bed50d227f590da2f1611dfd9437ac.jpg\" alt=\"\" width=\"334\" height=\"171\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2018\/12\/35bed50d227f590da2f1611dfd9437ac.jpg 800w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2018\/12\/35bed50d227f590da2f1611dfd9437ac-300x154.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2018\/12\/35bed50d227f590da2f1611dfd9437ac-768x394.jpg 768w\" sizes=\"auto, (max-width: 334px) 100vw, 334px\" \/><\/p>\n<p>To help students visualize wave motion, I have been developing interactive tools using the programming language Scratch. I have published about 40 projects so far, and you can try them all for free on <a href=\"https:\/\/scratch.mit.edu\/users\/KuwakoKen\/projects\/\">this site<\/a>. Today, I want to show you one featuring bees that is perfect for beginners.<\/p>\n<p>First, check out this tool for transverse waves.<\/p>\n<p><a href=\"https:\/\/scratch.mit.edu\/projects\/205914073\/\">The Transverse Wave Journey of the Bees<\/a><\/p>\n<p><iframe loading=\"lazy\" title=\"\u30d4\u30e7\u30f3\u30ad\u30fc\u3067\u6ce2\u306e\u52d5\u304d\u3092\u4f5c\u308d\u3046\uff08\u79d1\u5b66\u30d7\u30ed\u30b0\u30e9\u30df\u30f3\u30b0\uff09\" width=\"1140\" height=\"855\" src=\"https:\/\/www.youtube.com\/embed\/-WeZDKiBdnM?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>My favorite feature of this tool is the <b>slow-motion button<\/b>. When the wave travels to the right, you can clearly see that each individual bee is only moving up and down. Through the dance of these bees, you can really feel how the matter stays in place while only the energy is passed along to the next neighbor.<\/p>\n<h3>Solving the Mystery of Longitudinal Waves with Bee Faces<\/h3>\n<p>Next, let&#8217;s look at longitudinal waves (also known as compression waves), which often confuse students. Sound waves are a prime example. The struggle usually starts because we have a rule where we redraw these waves to look like transverse waves to make them easier to graph, which can be very disorienting.<\/p>\n<p><a href=\"https:\/\/scratch.mit.edu\/projects\/206388715\/\">Understanding Longitudinal Waves through Bee Directions<\/a><\/p>\n<p><iframe loading=\"lazy\" title=\"\u3088\u304f\u308f\u304b\u308b\uff01\u7e26\u6ce2\u306e\u6a2a\u6ce2\u8868\u8a18\uff08\u30d4\u30e7\u30f3\u30ad\u30fc\uff09\" width=\"1140\" height=\"855\" src=\"https:\/\/www.youtube.com\/embed\/qrY56tmDjeE?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>In this tool, I used the direction the bees are facing\u2014left or right\u2014to express the wave&#8217;s motion. By seeing which way the bees shift, you can instantly see where the air is compressed (crowded with bees) and where it is rarefied (the bees are sparse).<\/p>\n<h3>Mastering Graphs: Waves as Photos vs. Videos<\/h3>\n<p>The biggest hurdle in learning about waves is reading the graphs. It is essential to understand the difference between a snapshot of the wave&#8217;s shape at one moment (the y-x graph) and the recording of the vibration at a single point over time (the y-t graph).<\/p>\n<p><a href=\"https:\/\/scratch.mit.edu\/projects\/213576116\/\">Conquering Two Graphs Simultaneously<\/a><\/p>\n<p><iframe loading=\"lazy\" title=\"\u9055\u3044\u304c\u308f\u304b\u308b\uff1fy-x\u3068y-t\u306e\uff12\u3064\u306e\u30b0\u30e9\u30d5\uff08\u6ce2\u30b9\u30bf\u30fc\u30c8\u7248\uff09\" width=\"1140\" height=\"855\" src=\"https:\/\/www.youtube.com\/embed\/1wnoUbjbpuQ?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>I am also preparing new tools for an even deeper understanding.<\/p>\n<p><a href=\"https:\/\/scratch.mit.edu\/projects\/224259809\/\">Drawing Waves One Stroke at a Time<\/a><\/p>\n<p><b><span style=\"color: #ff0000;\">Currently, I am planning to build a new slow-motion tool where a single pulse is released at the touch of a button.
