Waves
Revision notes for Waves in AQA Physics (8463). Every lesson in BrainCake comes with R.E.C.I.P.E. recall steps, a quick check and spaced reviews.
- Transverse and longitudinal wavesWaves transfer energy from one place to another without moving the material they travel through.
- Properties of wavesWave motion is described using a few quantities.
- Reflection of waves (physics only)When a wave meets the boundary between two different materials, it can be reflected, absorbed or transmitted, and often more than one of these…
- Sound waves (physics only) (HT only)Sound waves can travel through solids as well as through air.
- Waves for detection and exploration (physics only) (HT only)Waves in solids and liquids differ in velocity, absorption and reflection.
- Types of electromagnetic wavesElectromagnetic waves are transverse waves.
- Properties of electromagnetic waves 1When electromagnetic waves meet a substance, the substance may absorb, transmit, refract or reflect them.
- Properties of electromagnetic waves 2Radio waves can be produced by oscillations in electrical circuits (Higher tier).
- Uses and applications of electromagnetic wavesEach type of electromagnetic wave has practical uses.
- Lenses (physics only)A lens forms an image by refracting light.
- Visible light (physics only)Each colour within the visible light spectrum has its own narrow band of wavelength and frequency.
- Emission and absorption of infrared radiationAll objects, whatever their temperature, emit and absorb infrared radiation.
- Perfect black bodies and radiationAll objects emit radiation.
