Waves in General
Patterns of energy that travel through matter and carry energy.
What are waves?
The highest part of a wave
What is a crest?
What is a reflection
The bouncing back of a wave when it hits a surface through which it cannot pass.
The part of the eye that transmits the electrical signal to the brain.
What is the optic nerve?
What happens to wave lengths if a waves frequency increases?
What is it gets shorter.
What are line waves?
The type of waves that move in parallel lines and start from one side, moving to the other.
The distance between crest to crest or trough to trough in a wave
What is a wavelength?
What is refraction?
The bending of light or other waves as they pass from one medium to another.
The part of the eye that allows light waves to enter (it gets larger or smaller depending on the amount of visible light).
What is a pupil?
A wave pattern that has many waves in a given amount of time has _______ frequency
What is high frequency.
The line running through the middle of the wave.
What is the midline?
The number of complete waves that pass a given point in a certain amount of time
What is frequency?
What is the definition of absorb?
The part of the eye that refracts the light waves.
What is the lens?
A tall wave has a ______ amplitude.
What is high?
The material through which a wave travels.
What is a medium?
What are the characteristics of a digital signal?
What is clear cut values, like numbers or dots and dashes. It is also easy to send and receive.
What color light waves make up white light? Write the acronym for the colors
ROY G BIV (red, orange, yellow, green, blue, indigo, violet)
The part of the eye that converts the light waves into electrical signals.
What is the retina?
An area that you cannot hear sound
What is the lowest part of the wave called?
The distance between the mid line and crest OR the resting point and trough
What is Amplitude?
What items are needed for radio wave communication?
Transmitter, receiver, and antenna.
Explain why we see an apple as red or green when the light that hits it is white.
When the white light hits the apple, it absorbs all light wave colors except red or green, which reflect off and hit your eyes. Your brain interprets the light wave as the color.
Why might you have a hard time using your cell phone if a storm ran through your neighborhood the night before?
*Possible answers* The towers might have been damaged in the storm, there might be too many people trying at the same time making the system lag, etc.
