Lesson 1
A disturbance that carries energy and travels in repeating patterns
to relocate
Transfer
To show up
Appear
To take in
Absorb
The part of the device that sends radio signals
Transmitter
The greatest height of a wave from its resting point
Amplitude
The amount of time it takes for a wave to complete one back and forth motion
Wave Period
A line of energy that continues in one direction until it hits an object
Ray
A message with information
Signal
The part of a device that takes in radio waves
Antenna
The distance between similar points on a wave
Wavelength
Waves that show up in a circle
Waves that move in a parallel line
Circular waves
Plane waves
When light rays bounce
Reflect
All the possibilities between two endpoints
Range
Converts radio waves to messages
Receiver
The number of wave repetitions in a certain amount of time
Frequency
A wave that moves perpendicular to the direction of the particles
A wave that moves in the same direction as the particles
Transverse
Longitudinal
When light rays bend
Refract
Lets no light through
Opaque
Signals that use clear cut values such as numbers
Digital
The top point of a wave is called the:
The bottom point of a wave is called the:
Crest
Trough
Waves meeting and combining amplitudes as they move
Superposition
A group of parts that work together as a whole
System
Lets some light thorugh, but not all light
Lets almost all light pass through and you can see through it clearly
Transparent
Signals that send information in a continuous stream
Analog
