AQA Physics Waves Revision Notes
Master AQA Physics Waves using simple revision notes, key facts and practice questions — all generated by AI for your exam.
Waves are disturbances that transfer energy from one place to another without the transfer of matter. They can be classified into mechanical waves, which require a medium, and electromagnetic waves, which do not.
Key Concepts
- 1Waves can be classified as transverse or longitudinal.
- 2The speed of a wave is determined by the medium through which it travels.
- 3Wavelength, frequency, and amplitude are key characteristics of waves.
- 4The principle of superposition explains how waves interact with each other.
- 5Reflection, refraction, and diffraction are fundamental behaviors of waves.
Simple Explanation
Waves are like ripples on a pond that move energy around without moving the water itself. They can be seen in things like sound and light. Waves can be different shapes, like waves in the ocean (which go up and down) or sound waves (which push and pull). Understanding how waves behave helps us explain many natural phenomena.
