What you'll learn
The properties and behaviour of waves.
Wave basics
- Transverse vs longitudinal waves (e.g. sound is longitudinal).
- Wave equation: v = f λ; frequency, wavelength, amplitude, period.
- Reflection of waves; sound needs a medium.
Exam tips
- Use v = fλ with matching units.
- Distinguish transverse and longitudinal with examples.
Common mistakes
- Saying sound travels through a vacuum.
- Confusing frequency and wavelength.
