WRITEFOCUS QUESTIONYour 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

CHECKTEST YOUR THINKINGRate 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.
