Parts of Radio
This is part of the device that sends out radio waves.
Transmitter
What is the crest in a wave?
What part of the eye lets light in?
The Pupil
Light rays that bounce off a surface and move in a new direction is called what?
A: Refract
B:Reflect
C:Prism
D: Absorbed
B: Reflect
True or False:
A medium does not help other waves travel easier.
False
Mediums DO help other waves travel
This is part of the device that takes in the radio waves (typically located at top of a tower and on transmitters)
Antenna
What is a wavelength?
Distance between similar points on a wave.
What part of the eye bends and focuses the light into images?
A: Refract
B: Reflect
C: Absorbed
D: Prism
A: Refract
What is a wave period?
The amount of time it takes for a wave to complete one back-and-forth motion.
This part of the device converts the radio waves into usable messages and turns signals into music, images, or data and make web pages.
What does amplitude mean?
What part of the eye receives the image from the lens and sends it to the brain?
The Retina
When light hits an object but is not reflected or refracted it is what?
A: Refract
B: Reflect
C: Absorbed
D: Prism
C: Absorbed
Circular waves create what type of pattern?
Circles or ripples
True or false:
Radio waves can send a signal, or a message wave with information, which carry waves from radio and TV stations, cell phones, and Internet satellites.
True
What is a trough on a wave?
The bottom part of a wave.
What part of the eye is connected to the brain?
The Optic Nerve
An object that lets some light in is called what?
A: Opaque
B: Translucent
C:Transparent
D:Invisible
B: Translucent
Plane waves create what kind of pattern?
Stripes or lines.
True or False:
ALL radio frequency devices include similar parts that work as a system. A signal MUST travel from one device to another.
True
One complete back and forth motion is what?
How are we able to see the colors of things?
When white light is REFLECTED off the object and hits our eye.
When matter lets no light in that is called what?
A: Opaque
B:Translucent
C: Transparent
D: Invisible
A:Opaque
Which color absorbs more light?
Black
