• Identify wave properties.

• Explain the relationship between frequency and wavelength.

• Describe the effect of different media on wave speed.

• Identify that light waves can be reflected, refracted or absorbed.

• Explain how frequency and pitch are related.

• Explain how loudness and amplitude are related.

• Interpret the electromagnetic spectrum.

• Identify, compare and contrast types of electromagnetic waves.
