What’s on the Particle in a Box poster
The rule, 3 worked examples, and the mistake everyone makes.
- A particle confined to a box has energies fixed by the box length and the quantum num…
- Eₙ = n²h²/(8mL²), n = 1, 2, 3 …
- Smaller box = Higher energies
- Ground state = n = 1, never zero
- Heavier particle = Lower energies
- Common mistake: Expecting a ground state of zero energy → The minimum is n = 1, not n…
This model explains quantum dot colours: smaller dots have larger level gaps and emit bluer light.

- Who is the Particle in a Box poster for?
- Particle in a Box belongs to the Physics section rather than to a school year, because physical science is not something one grade owns. Anyone learning quantum can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Particle in a Box poster?
- Confinement produces quantised energy. The box shows exactly why. A wall chart earns its place by being glanceable from where the work is happening, so Particle in a Box belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Particle in a Box?
- Quantum Numbers, Blackbody Radiation and Conservation Laws sit alongside Particle in a Box in the Physics section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Quantum NumbersBlackbody RadiationConservation Laws
- Is the Particle in a Box poster free to download and print?
- Yes. Particle in a Box downloads as a free PDF with no account, no email and no watermark, like everything else in the Physics section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Particle in a Box poster print at?
- Particle in a Box is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Particle in a Box loses nothing.Printing guide
