Waves🌊 Flashcards
Cycle Test Week 5 Preparation
Define a wave simply.
A disturbance that moves energy from one place to another.
What is the substance that waves move through called?
The medium.
List 4 types of Mediums, and give an example of each:
1) Gas (air)
2) Liquid (water)
3) Solid (rope)
4) Vaccum
What is the high point of a wave called?
The crest.
What is the low point of a wave called?
The trough.
What is the word to describe the movement of water moving back and forward, creating crests and troughs?
Oscillation.
Define a Pulse Wave.
Waves caused by a one time/single disturbance.
What do you call waves caused by a one time/single disturbance?
A Pulse Wave.
Define a Periodic Wave.
Waves that are caused by a periodical, continuous or repetitive disturbance.
What do you call waves that are caused by a periodical, continuous or repetitive disturbance?
A Periodic Wave.
Define a Transverse Wave.
Wave that consists of a disturbance occurring perpendicular to the travel direction of the wave.
What do you call a wave that consists of a disturbance occurring perpendicular to the travel direction of the wave?
A Transverse Wave.
In Transverse Waves the coils travel in the same direction as the wave - True or False?
False, they do not travel in the same direction as the wave.
Why don’t the coils travel in the same direction of the wave in a Transverse Wave?
They only move up and down.
Where does the wave originate?
The source. e.g a hand moving up and down.
In transverse waves the direction of the wave makes what angle with the movement of the source?
90 degrees/ a right angle.
All electromagnetic waves are ___________ waves.
Transverse.
All ____________ waves are Transverse.
Electromagentic.
Give 2 examples of Transverse waves:
Light, Microwaves. (Infrared, Radio)
Define Longitudinal Waves.
Waves that consist of a disturbance occurring parallel to the direction of the wave.
In Longitudinal Waves the disturbance occurs in what direction of the wave?
Parallel to the wave.
In longitudinal waves the coils move in what directions?
Left and right.
The wave travels _____ from the source.
Away.
Give 2 examples of Longitudinal waves:
Sounds Waves, Vibrations in a spring. (Ultrasound, Pressure waves)
