波与不同材料
Waves & Different Materials
解释波如何被不同材料吸收、透射或反射，并运用这些相互作用来解释颜色感知、视觉、通信技术，以及不同表面对波行为的影响。
Explain how waves can be absorbed, transmitted, or reflected by different materials, and apply these interactions to explain colour perception, sight, communication technologies, and the effects of different surfaces on wave behaviour
学习证据 / Evidence
- 解释波的吸收、透射和反射之间的区别
- 运用这三种相互作用来解释我们如何看到有颜色的物体
- 解释无线电波、可见光和红外线如何用于不同的通信技术
- 描述表面的特性（颜色、质地、材料）如何决定它与辐射相互作用的方式
- Explains the difference between absorption, transmission, and reflection of waves
- Uses the three interactions to explain how we see coloured objects
- Explains how radio waves, visible light, and infrared are used in different communication technologies
- Describes how the properties of a surface (colour, texture, material) determine how it interacts with radiation
评估问题 / Assessment
如果{{name}}在晴天穿着一件黑色T恤，而一位朋友穿着白色T恤，{{name}}能否用波的相互作用来解释为什么黑色T恤更热？材料的哪些特性决定了它们吸收或反射辐射的方式？
If {{name}} was wearing a black t-shirt on a sunny day and a friend was wearing white, could they explain using wave interactions why the black shirt gets hotter — and which properties of materials determine how they absorb or reflect radiation?
