Wave Properties: Amplitude, Frequency, and Wavelength (Parent Q&A)

This guide supports conversations about how scientists describe waves. Encourage the learner to use definitions, labelled diagrams and units rather than judging a wave by appearance alone. Some effects, such as loudness, depend partly on perception and context, so the lesson uses careful wording. It compares water waves, sound, light and radio signals without suggesting that all waves behave identically.
