Wave Properties and Behaviour
Relating wavelength, frequency, speed and amplitude and explaining reflection, refraction, transmission and absorption.
How to study for GCSE Combined Science
Build the three sciences as connected disciplines, practise mathematical and practical reasoning, then apply the common core to the exact tier and paper structure of your current specification.
Core concepts
Concept 1
Waves transfer energy and information without net transfer of matter, and may be transverse or longitudinal.
Exam cue: Mark wavelength between equivalent phase points and keep frequency distinct from speed.
Concept 2
Wave speed equals frequency times wavelength, with frequency set by the source and speed set by the medium.
Exam cue: Explain refraction through a speed change at a boundary, not a force toward the normal.
Concept 3
Reflection, refraction, absorption and transmission depend on the wave, boundary and material.
Targeted study blocks
Tier coverage
Foundation core with Higher-tier extensions
Higher-tier demand can include multistage wave calculations, wavefront reasoning and less familiar material interactions.
Risk pitfalls and guardrails
Saying particles travel with the wave from source to receiver.
Guardrail: Do not import separate-science content or another route's paper order; use the full physics equations sheet required for current specifications while checking the exact series materials and entered tier.
Assuming frequency changes whenever a wave enters a new medium.

Memory anchors
Transverse wave
A wave whose oscillations are perpendicular to energy transfer.
Longitudinal wave
A wave whose oscillations are parallel to energy transfer.
Wavelength
Distance between adjacent points in the same phase.
Wave frequency
Number of complete oscillations passing per second.
Wave speed
Frequency multiplied by wavelength.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
