WRITE FOCUS QUESTION Your initial thinking
Engineers designing a hospital discovered that metal walls blocked WiFi signals (~0% transmission) while glass windows allowed ~90% through. To build reliable patient-monitoring communication systems, they must understand how wave properties and material choices interact.
How do wave properties and material interactions determine whether information can be reliably transferred through a communication system?

Q1: Name one wave property (wavelength, frequency, or amplitude) and explain how it determines whether a wave is transmitted, reflected, or absorbed by a material. Use evidence from your synthesis review.

CHECK TEST YOUR THINKING Rate each: FALSE ← 1–2–3–4–5 → TRUE
1. Ocean waves carry water molecules forward with them — you can see sand and debris moving toward shore with each incoming wave, which proves the wave is transporting matter.
2. Light travels so fast that it effectively reaches Earth from the Sun at the same moment it is emitted — the 8-minute travel time is only measurable with advanced instruments, not in everyday experience.
3. All electromagnetic waves travel at the same speed in a vacuum and obey the same wave equation, so they all interact with materials in the same predictable way regardless of wavelength or frequency.
4. Digital signals encode information as exact 1s and 0s, so a signal either arrives perfectly intact or not at all — unlike analog signals, digital encoding prevents any gradual degradation during transmission.
5. Reflection requires a perfectly smooth surface so that incoming waves bounce back at the correct angle — rough or non-shiny surfaces scatter or absorb waves rather than reflecting them.
