Catch the Wave
A regular pattern of up and down or back and forth motion.
What is a wave?
The highest point of a wave above the baseline.
What is the crest of a wave?
The ability to keep an object in the one general area.
What is consistency?
To exchange information using a common code.
What is to communicate?
Represents text, computer instructions, or other data using any two-symbol system, often 0 and 1.
What is binary code?
Needed by a wave to initiate its pattern of motion.
What is energy?
The lowest point of a wave below the baseline.
What is the trough of a wave?
The object moves up and down, or side to side, but no forward motion of the object. The average change in position of an object over time.
What is net motion?
A communication that is sent to a person who cannot be contacted directly.
What is a message?
A person or device that interprets an audio or visual signal.
What is a receiver or decoder?
Sound waves, water waves, electromagnetic waves, microwaves, radio waves, light waves, etc.
What are types of waves?
The distance measured from one part of a wave to the same spot on the next wave.
What is the wavelength of a wave?
The number of cycles (wavelengths) per second of time.
What is frequency?
A method for transmitting information that uses sequences of short and long beeps to represent the letters, numerals, punctuation, and special characters of a message.
What is Morse code?
Forms of communication used now.
What are telephones, cell phones, text messaging, email, walkie-talkies, video meetings (Zoom, FaceTime)?
A regular or repeated form or design.
What is a pattern?
The height to the "top" of a crest or the "bottom" of a trough from the resting line (baseline).
What is amplitude?
The repeated up and down, or back and forth pattern.
What is the motion of a wave?
A wave used for long distance communication.
What are radio waves?
A PC (personal computer) and cell phones translate these almost instantaneously to the human senses.
What is binary code back to alpha-numeric (alphabet letters and numbers)?
A kind of movement like a vibration or shaking motion that moves energy from one place to another.
What is a wave?
Change in wave amplitude and wavelength, shown by this when the volume, or frequency changes.
What an oscilloscope shows?
In the experiment, the tank, amount of water, and the bobber.
What are the controlled variables?
Waves sent out, or broadcast the message.
What is transmitted?
The use of these allows communication to be faster, better reception, and have more capabilities.
What are the use of binary code, radio waves, satellites, and more technology?
