AI image models can produce striking conceptual physics visuals but cannot draw a quantitatively correct diagram, so these prompts target atmosphere and metaphor rather than anything a student would measure off.
Physics splits neatly. Wave interference, field lines and orbital motion make beautiful abstract images. Free-body diagrams, vector arrows and anything with a number on it do not, and never will while text rendering is what it is.
What this cannot do
Arrows are the specific trap. Ask for a force diagram and you will get arrows of arbitrary length pointing in arbitrary directions, which is worse than no diagram because it looks authoritative. Anything where the geometry carries meaning should be drawn in a vector tool or generated from data.
5 prompts
Wave interference, abstract
Wave, sound and optics sections.
Two sets of concentric circular ripples spreading across a dark surface and overlapping into an interference pattern, thin luminous lines on near-black, precise and geometric, subtle cyan glow, high contrast, no text
Things to change
β "three sources" for a more complex pattern
β "warm gold on cream" to soften it
Magnetic field lines
Electromagnetism topics and section dividers.
Elegant looping field lines curving from one pole to another around an unseen centre, fine glowing filaments against deep blue-black, symmetrical and clean, scientific visualisation aesthetic, volumetric light, no labels
Things to change
β "iron filings on paper, macro photograph" for a real-world version that is also accurate
Orbital mechanics, minimal
Gravitation and astronomy sections.
Minimal diagram of elliptical orbital paths around a small bright central point, thin white lines on deep navy, generous empty space, precise geometric style, faint grid in the background, no text or numbers
Things to change
β "several nested orbits" for a system
β "blueprint style, white on cyan" for a technical feel
Pendulum motion, long exposure
Oscillation and simple harmonic motion. Photographic, so it cannot be factually wrong.
Long exposure photograph of a swinging pendulum tracing a luminous arc through a dark room, light trail sharp and continuous, single point of light at the bob, everything else in shadow, minimal composition
Things to change
β "Foucault pendulum, wide shot" for scale
β "multiple exposure" for discrete positions
Refraction through glass
Optics and Snell's law sections. A real optical effect, so it renders convincingly.
Macro photograph of a beam of white light entering a triangular glass prism and splitting into a spectrum on the far side, dark background, visible light path through slight haze, sharp focus on the prism edge
Things to change
β "laser through water" for total internal reflection
β "soap film interference colours" for thin-film optics
Common questions
Can AI draw a free-body diagram?
Not usefully. Arrow lengths and directions carry the meaning in a free-body diagram, and image models place arrows decoratively. The result looks like a diagram and says nothing true, which is worse than an obviously rough sketch.
What physics subjects generate well?
Anything where the image is atmospheric rather than measured: field lines, wave patterns, orbital paths, light trails, optical effects. Physical photography of real phenomena β prisms, pendulums, iron filings β is strongest of all.
How do I get a diagram with correct proportions?
Generate it from data rather than from a prompt. A plotting library will draw a wave, an orbit or an energy curve to scale, and you can style it afterwards. Image models are for the header, not the figure.
