光繞射模擬器：單縫與圓孔圖樣

Welcome to Billy Sir’s Interactive Physics Masterclass. In this interactive guide, we will explore the fascinating wave nature of light through diffraction. When light passes through a narrow aperture like a single slit or a pinhole, it bends and spreads out, creating a distinct pattern of bright and dark fringes.
歡迎來到 Billy Sir 的互動物理大師課。在這個互動指南中，我們將透過繞射現象來探索光迷人的波動性質。當光穿過如單縫或圓孔等狹窄孔徑時，它會彎曲並散開，形成明暗相間的獨特圖樣。

How does aperture size affect diffraction?
Adjust the sliders below to see how changing the wavelength ($\lambda$) or the aperture size affects the spread of the light. Notice that a smaller aperture causes the light to spread out even more!
孔徑大小如何影響繞射？
調整下方的滑桿，觀察改變波長 ($\lambda$) 或孔徑大小如何影響光的擴散。請注意，較小的孔徑會導致光散開得更廣！

Why does white light create colored fringes?
White light is composed of many different wavelengths (colors). Because longer wavelengths (like red) diffract at greater angles than shorter wavelengths (like blue), the colors separate, creating a beautiful rainbow effect at the edges of the pattern.
為什麼白光會產生彩色條紋？
白光由許多不同波長（顏色）組成。因為較長的波長（如紅光）比較短的波長（如藍光）繞射的角度更大，所以顏色會分離，在圖樣邊緣形成美麗的彩虹效果。
