Wave Parts
The highest point of a wave.
What is the crest?
This increases when a sound gets louder.
What is amplitude?
Lily felt the boat do this as waves passed under it (two words).
What is rise and fall?
Computers convert sounds into patterns of these two symbols.
What are 0s and 1s (binary)?
Define amplitude in your own words (one sentence).
What is: The height of a wave measured from the middle (rest) to a crest or trough?
What is the trough?
Waves with a shorter wavelength have a higher ______ sound.
What is pitch?
A material you could use to build a 3‑D model of a wave.
What is clay (or modeling foam, sand + foam, toothpicks + clay)?
Morse code uses these two basic marks.
What are dots and dashes?
Draw a short sketch of a wave with higher pitch — then explain why the pitch is higher.
What is: Waves closer together (shorter wavelength); higher pitch because more cycles occur per time?
The distance from the middle point of a wave to either the crest or trough.
What is amplitude?
This describes how waves carry energy but usually not the water itself across a pond.
What is energy transfer?
True or False — Waves always push floating objects all the way across a pond.
What is False?
True or False — A computer sends voice by turning the sound into 0s and 1s that can be sent and rebuilt.
What is True?
Draw a wave with larger amplitude — then explain how volume changes.
What is: Taller peaks and deeper troughs; volume is louder because amplitude is larger?
The distance from crest to crest.
What is wavelength?
Name two measurements you would label on a wave diagram.
What are amplitude and wavelength?
When waves have more energy they often have larger _______.
What is amplitude?
One similarity between Morse code and binary (short answer).
What is: Both use patterns of simple symbols to represent information that can be sent and decoded?
Explain why a floating duck mostly moves up and down when waves pass instead of being carried across (one sentence)
What is: Waves move energy through the water while the water particles move in roughly circular/up‑and‑down paths, so the duck rises and falls rather than traveling across?
The point halfway between a crest and a trough.
What is the rest (or equilibrium)?
Explain briefly why windy days create bigger waves (one‑sentence answer).
Wind adds energy to the water, increasing wave amplitude (making waves taller)
Give one real example where waves transfer energy (short answer).
What is: ocean waves moving a boat up and down; sound waves making a speaker vibrate; light waves warming your skin? (any correct example)
Compare (briefly) a walkie‑talkie and a computer for sending voice over distance (one or two sentences).
What is: A walkie‑talkie sends analog or radio signals directly over short distances; a computer converts voice to digital signals (binary) and can send them farther via networks?
Short paragraph (2–3 sentences): Compare and contrast digital signals and Morse code, including one similarity and one difference.
What is: Both systems encode information as patterns of symbols that can be sent and decoded. Morse uses dots/dashes to represent letters historically for telegraphs; digital uses binary 0s/1s to represent many kinds of data for electronic devices.
