Subject outcome
Subject outcome 3.1: Describe and apply properties of waves in everyday life contexts
Learning outcomes
- Identify and describe the basic concepts of the Doppler effect with sound and ultrasound.
- Apply the Doppler effect to radar and examples of sonic boom.
- Define EM radiation; identify the EM spectrum and identify examples (light, radio waves, microwave, IR, UV and others) and their application.
- Describe the dual nature of EM radiation; i.e. wave and particle nature.
- Identify the relationship of wavelength to frequency to explain colour and energy of light.
- Define lasers and give examples of its application.
- Explain and apply the photoelectric effect give examples of its application.
