惑星AR vs Optical Path

太陽から地球までの距離はどれくらいか知っていますか？ 数値としては学校で習っても、 体感的にどれくらいの距離かをすぐに想像できる方は少ないと思います。 大きさや距離を感覚で理解したい方のために、このアプリを作成しました。 太陽系についての理解が深まる手助けとなれば幸いです。 ＜操作説明＞ 大きさ基準モード（惑星のサイズ比率を合わせて表示） 距離基準モード（惑星の距離比率を合わせて表示） 公転モード（惑星の公転の様子を表示） の3種類のモードがあります。 指で動かせるので、視点を変えて回転させたり、 2本指で拡大縮小もできます。 ＜その他の機能＞ ・各惑星の詳細情報、クイズ形式の豆知識付き ※公転モードは、36秒で約1年間となっています。

This program is designed to illustrate the laws of reflection and refraction of light. As the laser pointer moves, the laser beam enters from the upper medium into the lower medium. When the two media differ, both reflection and refraction phenomena occur. When the refractive index of the upper medium is greater than that of the lower medium, and the angle of incidence exceeds the critical angle, a fascinating total internal reflection can be observed. This program is suitable for primary and secondary school students to learn and understand the laws of reflection and refraction of light, allowing them to review and reinforce physics concepts through engaging interactive activities. It can also be utilized by teachers for classroom demonstrations, enhancing lessons with a more lively and dynamic approach. The program's key features include: 1. Demonstration of reflection and refraction laws when the upper and lower media differ: The angle of reflection equals the angle of incidence, and the ratio of the sines of the angles of incidence and refraction equals the ratio of the refractive indices of the lower and upper media. 2. Demonstration of total internal reflection when the refractive index of the upper medium is greater than that of the lower medium: When the angle of incidence exceeds the critical angle, all incident light is reflected back, with no refracted light. 3. Selection of five laser colors - red, blue, green, orange, and purple - each corresponding to a unique refractive index. Lasers with higher frequencies exhibit greater refractive indices.
