Turn your light unit notes into an editable mind map
Upload notes or a PDF and get a branching map of reflection, refraction, lenses, and the spectrum that you can edit and explore.
Why a light mind map suits a physics unit
Light is one of the most connected topics in a first physics unit, since reflection, refraction, lenses, and the electromagnetic spectrum all build on each other. A light science mind map puts those ideas on one page so you can see how the branches relate. If you were hoping for a ready-made printable, you can instead upload your own lecture notes or textbook PDF and get a map built from that material.
- Covers reflection, refraction, dispersion, lenses, and the spectrum from your own notes
- Editable nodes so you can match your teacher's terms and definitions
- Works from PDFs, DOCX, PPTX, plain text, and photos of pages
- Free plan includes 3 generations per month with no credit card needed to start
Upload your own material
Drop in a PDF, DOCX, PPTX, plain notes, or a photo of a textbook page.
Editable branches
Rename, move, or delete nodes so the map matches your teacher's version of the unit.
Explorable structure
Follow each branch from the main idea to its details and see how reflection, refraction, and lenses connect.
How it works
Add your light notes
Upload a PDF, slide deck, or photo of your handwritten or printed notes.
Generate the map
DeckOwl builds a branching map of the main ideas and their sub-points.
Edit and explore
Adjust branches to fit your class, then move through the map to review each concept.
Mind maps suit light because the topic is a web of cause and effect: change the medium and refraction follows, change the lens shape and the focal behavior shifts. DeckOwl keeps the map editable, so you can add a branch for an example from class or remove one you do not need.
Because each branch can be explored on its own, the map works as a review tool before a quiz. Start with the main branches, then fill in the sub-points from your notes until the map matches what your teacher covered.

Frequently asked questions
What are the main branches in a light mind map?
Most units split into reflection, refraction, dispersion, lenses, and the electromagnetic spectrum. Starting with those five makes it easier to hang your own sub-points underneath.
How do I remember the law of reflection for a test?
The angle of incidence equals the angle of reflection, and both are measured from the normal line rather than the surface. Redrawing a ray diagram from memory a few times is a quick way to check yourself.
Can I export a light mind map?
Exporting is a paid feature. The free plan lets you study in the browser, while Plus at $39 per year or $7.99 per month adds PDF, DOCX, Anki, and CSV export.
Does the free plan include mind maps?
Yes, the free plan includes 3 generations per month, and you can study the results in the browser. Unlimited generations start with Plus.
