Waves · Chapter

Waves

Explore wave motion, superposition, sound, light, and the electromagnetic spectrum through dynamic models.

Start chapter Next: Electricity and Magnetism

Learning Path

Checkpoint 1: Wave motion

Describe Waves

Start with displacement-time and displacement-distance views, then connect frequency, wavelength, period, and speed.

Checkpoint 2: Light

Model Light

Use ray and wave models to reason about reflection, refraction, lenses, colours, and image formation.

Checkpoint 3: Sound

Hear and Measure

Connect pressure variations, frequency, amplitude, resonance, and Doppler effects to what we hear.

Checkpoint 4: EM spectrum

Extend the Spectrum

Relate visible light to electromagnetic waves with different wavelengths, uses, and hazards.

Chapter Lens

How do repeated disturbances transfer energy and information through waves, light, and sound?

A wave transfers energy without transferring matter from source to receiver overall.
Frequency, wavelength, period, speed, and amplitude describe different measurable features of wave motion.
Reflection, refraction, diffraction, and interference help explain light, sound, and electromagnetic phenomena.

Misconception Watch

Wave speed, frequency, wavelength, and amplitude are related but not the same quantity.
Particles in a medium do not usually travel with the wave from source to receiver; they oscillate locally.
A brighter light or louder sound means larger amplitude, not necessarily higher frequency.

Chapter Concept Checks

1. A water wave travels across a tank. What is mainly transferred from one side to the other?

Answer: Energy is transferred while the water particles mostly oscillate about their positions.

Distractors to watch for: The same water particles travel all the way across the tank. / Only mass is transferred, not energy. / Nothing is transferred because particles return to their starting positions.

2. If the frequency of a wave increases while wave speed stays constant, what happens to wavelength?

Answer: The wavelength decreases.

Distractors to watch for: The wavelength increases. / The wavelength stays the same. / The amplitude must become zero.

3. Which behaviour shows that waves can overlap and combine?

Answer: Interference or superposition.

Distractors to watch for: Mass density. / Chemical reaction. / Uniform acceleration.

Adaptive Suggestion

If this chapter feels hard, study the first few interactives and use the concept checks until your streak improves. If it feels easy, jump to resources with videos or OSPSG links and explain the model evidence in your own words.
