What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.

Diffractiondepends onWaveEstablished
diffraction depends on Wave.
Mechanism: Diffraction is the bending and spreading of any wave around obstacles or through openings.

Doppler effectdepends onWaveEstablished
Doppler effect depends on Wave.
Mechanism: The Doppler effect is a wave phenomenon: motion between source and observer squeezes or stretches the waves, raising or lowering their pitch or colour.

WaveenablesEnergy transferEstablished
Waves carry energy from place to place.
Mechanism: A wave moves energy without moving matter far: sunlight warms the Earth and a shout reaches your ear because each is a wave transferring energy.

Interferencedepends onWaveEstablished
interference depends on Wave.
Mechanism: Interference is what happens when two waves overlap and their amplitudes add or cancel.
- University Physics (OpenStax) verifiedmoderate evidence
Polarizationdepends onWaveEstablished
polarization depends on Wave.
Mechanism: Polarization is a property of transverse waves: it describes the single direction in which the wave oscillates as it travels.

System context
Amplitudeis part ofWaveEstablished
Amplitude is the size of a wave's swing.
Mechanism: Amplitude is a property of a wave: the size of its swing from the resting line, which sets how loud a sound or bright a light is.

Electromagnetic radiation is a wave.
Mechanism: Electromagnetic radiation is a wave: oscillating electric and magnetic fields travel together through space at the speed of light.

Gravitational waveis aWaveEstablished
gravitational wave is a kind of Wave.
Mechanism: A gravitational wave is a ripple in spacetime itself — a wave that stretches and squeezes space as it passes, produced by violently accelerating masses.

Oscillationis part ofWaveEstablished
A wave is built from oscillations passed along.
Mechanism: Each point in the medium oscillates and nudges its neighbour, so the oscillation — and its energy — travels onward as a wave.

Sound waveis aWaveEstablished
A sound wave is a kind of wave.
Mechanism: Sound is a pressure wave: vibrating air passes the disturbance from molecule to molecule, exactly the wave pattern seen across physics.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Directly enables 1 concept; following enables/causes relations, 1 concept is downstream across 5 disciplines.
structural · Follows only enables/causes dependency edges — not general relatedness.
Currently dark in the atlas: no key date stored · 11 of 11 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Exercises 2 annotated mental models — a concept that connects several thinking patterns.
curated · Curated annotations, not a derived measure.
Structural neighbourhood: 11 → 68 → 235 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.

- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural

A wave is a travelling wobble that carries energy from one place to another. The water, air or string it moves through mostly stays put — only the disturbance moves along.

Waves
A disturbance that travels and carries energy from place to place without carrying the material itself along with it.
The wave moves; the stuff it moves through mostly stays put — like a ripple crossing a pond.
Oscillation
A repeated back-and-forth movement around a central value. How often it repeats is its frequency; how far it swings is its amplitude.
Look for something that keeps returning to where it started: a swing, a heartbeat, a vibrating string.
