Create a bold, highly legible vertical 2:3 high school physics poster comparing how waves behave when they meet boundaries, enter new media, pass through gaps, and overlap. Build the composition from four broad horizontal geometric bands, each with a distinctly different internal structure rather than repeated cards: a diagonal mirror layout for reflection, a split-medium layout for refraction, a narrow-gap layout for diffraction, and an overlapping-wave layout for interference. Use oversized typography, wavefront lines, boundary shapes, angle markers, and direction arrows as the main visual language. Keep the design fully graphic and diagrammatic, with no human characters, laboratory photography, conventional title banner, or central hero object.
Place “WAVES”, “AT”, and “BOUNDARIES” vertically along the far-left edge as the main title treatment. Near the bottom, add the horizontal subtitle “Reflection • Refraction • Diffraction • Interference.”
In the reflection band, show parallel wavefronts meeting a flat barrier and reflecting away. Add the large heading “REFLECTION” and the rule “Angle of incidence equals angle of reflection.” Include one clear normal line, matching incident and reflected angles, and large direction arrows. In the refraction band, show wavefronts crossing into a medium where wave speed changes. Add “REFRACTION” and “Changing speed changes wavelength and direction.” Keep frequency unchanged while the wavelength and travel direction change consistently across the boundary. In the diffraction band, show straight wavefronts passing through a narrow gap and spreading into curved wavefronts. Add “DIFFRACTION” and “Spreading increases when the gap is relatively small.” In the interference band, show two circular wave sources producing a clean overlapping pattern. Add “INTERFERENCE” and “Overlapping waves can reinforce or cancel.” Clearly distinguish constructive and destructive interference without suggesting that destructive interference permanently removes energy.
Add one large glossary strip along the lower edge containing exactly these four comparisons: “BOUNDARY → REFLECTION”, “NEW MEDIUM → REFRACTION”, “GAP OR EDGE → DIFFRACTION”, and “OVERLAP → INTERFERENCE.”
Use polished flat educational graphics with generous spacing and strong horizontal rhythm. Apply four controlled color combinations across the bands: navy and yellow, teal and coral, violet and mint, and black with electric blue, all on an off-white background. Keep wavefront spacing and direction cues internally consistent, do not show frequency changing during refraction, do not confuse diffraction with refraction, and do not show reflection without a boundary. Use exactly four major headings, four short rules, and one comparison strip, with oversized typography and no dense explanatory paragraphs.
