Minimalist infographic poster showing how a rainbow forms

Educational infographic poster titled "How a Rainbow Forms" in portrait layout, designed as a minimalist infographic with sharp, readable English text in clean sans-serif typography. Create a detailed cutaway technical diagram for kids ages 8–12, using 9 clearly numbered stages with bold headings, one-line captions, and precise visual elements. Show a clear top-to-bottom learning flow with large sequence numbers, curved arrows, dotted light paths, and directional labels connecting each step. Visual style: bright, friendly, educational, highly organized, vibrant rainbow palette over a clean light background, magazine-grade editorial illustration, vector-clean lines, no photographic textures.

1. heading: "Sunlight", caption: "White sunlight travels toward a floating raindrop.", visual: a simple sun icon at the top left emitting a straight white beam toward a large central cutaway raindrop.
2. heading: "White Light", caption: "Sunlight contains many colors mixed together.", visual: a narrow white beam with a small inset spectrum bar beside it, labeled as mixed light, pointing into the raindrop.
3. heading: "Enter the Drop", caption: "Light bends as it enters water from air.", visual: close-up cutaway of the beam crossing the raindrop surface and changing angle at the boundary, with a curved refraction arrow.
4. heading: "Slow Down", caption: "Light moves more slowly in water than in air.", visual: a mini comparison diagram with air outside and water inside the drop, using short motion lines and a speed arrow becoming shorter inside the drop.
5. heading: "Split Colors", caption: "Different colors bend by different amounts.", visual: the white beam separating into rainbow bands inside the droplet, with red bending least and violet bending most, shown by distinct colored paths.
6. heading: "Bounce Inside", caption: "The colors reflect off the back of the raindrop.", visual: internal reflection at the rear inner surface of the drop, with rainbow rays bouncing sharply and a mirror-like reflection arrow.
7. heading: "Bend Again", caption: "The colors bend again as they leave the drop.", visual: rainbow rays exiting the droplet at different angles, with the outgoing fan of colors clearly spreading outward.
8. heading: "Rainbow Angle", caption: "Red and violet leave at special angles to your eyes.", visual: angle diagram outside the drop showing an eye icon, a red ray near 42° and a violet ray near 40°, with simple angle arcs.
9. heading: "See the Rainbow", caption: "Many raindrops together make the rainbow you see.", visual: wide lower panel showing many small raindrops in the sky, each sending one color toward the viewer, forming a full curved rainbow arc over a simple landscape.

Include small supporting labels placed near diagrams: "air", "water", "refraction", "reflection", "red", "orange", "yellow", "green", "blue", "indigo", "violet", "42°", "40°". Keep every label crisp and large enough for easy reading. Use clean geometric shapes, thin technical callout lines, soft shadows only if needed, and balanced spacing so the poster feels minimalist despite the detailed science content. No logos, no copyrighted characters, no identifiable people, no medical imagery. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no watermarks Render labels and headings in clean English typography (sans-serif). No real-brand logos, no copyrighted characters, no people that could be identified, no graphic medical content. If the topic touches a regulated domain (medicine, finance, law), keep the explanation conceptual and add no specific dosages, prices or legal advice.
