波的行为词汇
Wave Behaviour Vocabulary
使用关于波的行为的科学词汇——折射、吸收、反射、散射、振幅、频率、波长、回声、光谱、入射角、反射角——并运用这些词汇来解释光和声音如何传播，以及它们如何与不同材料相互作用。
Use technical vocabulary for wave behaviour — refraction, absorption, reflection, scattering, amplitude, frequency, wavelength, echo, spectrum, angle of incidence, angle of reflection — and apply these when explaining how light and sound travel and interact with different materials
