Choices (one per line; prefix correct one with * ) * 0.48 µm 9.66 µm 1.0 µm 0.10 µm

Plain English answer (default view) — what you'd actually write on the test

🔬 Technical version / model bullets (revealed on click) — one bullet per line λ_max = 2897.8 / 6000 ≈ 0.483 µm (visible green-blue).

💡 Mnemonic / memory aid (shown on hover) Sun peak = 0.48 µm (visible). Earth peak = 9.66 µm (thermal). Don't swap them. Big 9.66 goes with COOL Earth.
