PS4B - 炼金辐射


In this video Paul Andersen describes some of the properties of electromagnetic radiation. The electromagnetic spectrum varies by wavelength from radio waves to gamma rays. We only see a portion of the spectrum known as visible light. A number of phenomenon (including refraction, emission spectrums, and gamma radiation) are discussed.

下一代科学标准物理科学纪律核心思想4B - 电磁辐射

在这个视频中,Paul Andersen描述了一些电磁辐射的特性。电磁谱通过从无线电波到伽马射线的波长而变化。我们只看到称为可见光的一部分。讨论了许多现象(包括折射,发射光谱和伽马辐射)。
