Information is sent directly from one cell phone to another.
What is
The lowest part of a wave between crests
What is trough
What is natural and manmade
Computer and other electronic devices transfer information in the form of patterns containing 1's and 0's.
What is binary code
The highest point on a wave, also called the crest
What is a wave peak
When light bounces off the surface of an object
What is Light reflection
Clear covering of the eye.

Sends and receives patterns that help our electronics work
Opening that let's light in
What is the pupil
When a wave moves forward and back (like sound waves)
What is Longitudinal waves
Allowing light, but not detailed shapes, to pass through
What is translucent
To convert a code into something people can understand.
The distance between wave peaks, measured from peak to peak.
What is wavelength
Tiny lights that make up the screens of our devices which can be turned on and off to form an image
What are pixels
Bends light to help you focus on an object
What is Lens
When a wave moves up and down (like the ocean waves)
What is transverse wave
Allowing light to pass through so that objects behind can be seen
What is transparent
A signal that can be sent through the air to send and receive information
What is radio waves
The height of a wave measured from the wave's resting point to the peak of the wave.
What is amplitude
The process of giving a computer instructions in a language it can understand, also called coding
What is computer programming
Gathers information about an object. Sends information to the brain
