Science Waves, Light & Soundusually ages 11–12

Wave Properties & Types

Describe waves in terms of amplitude, wavelength, frequency, and wave speed; distinguish transverse waves (oscillation perpendicular to direction of travel) from longitudinal waves (oscillation parallel); and use the wave equation v = fλ

How to tell they’ve got it

Tick these off as you see them — no test required.

Labels a wave diagram with amplitude, wavelength, crest, and trough
Distinguishes transverse and longitudinal waves and gives an example of each
Uses v = fλ to calculate wave speed, frequency, or wavelength given the other two
Explains what happens to wavelength if frequency increases while wave speed stays constant

Try this together

If your child was asked to describe a wave and how fast it travels, could they sketch one, label the wavelength and amplitude, and use the wave equation to work out speed from the frequency and wavelength?

Wave Behaviour Vocabularyages 9–11Describing waves in terms of amplitude, wavelength, and frequency requires these exact terms

Waves & How They Moveages 9–10Wave properties and the wave equation build directly on the wave model (amplitude, wavelength, frequency) introduced in upper KS2/early secondary

Vibrations & Soundages 6–9Vibrating materials producing sound is a concrete anchor for understanding wave motion

How Sound Waves Travelages 11–12Describing sound as a longitudinal pressure wave requires the general wave properties framework

The Electromagnetic Spectrumages 12–13The electromagnetic spectrum is understood as a family of transverse waves — requires the general wave properties framework

Waves & Different Materialsages 12–13Wave interactions with materials (absorption, transmission, reflection) require the wave properties framework
