1
A straight arrow that represents the direction a light wave travels.
Light Ray
A curved transparent object that bends light in specific ways.
Lens
A part of the electromagnetic spectrum in which light waves within a certain range of frequencies can be detected by the human eye.
Visible Light
The range of frequencies and wavelengths of all light waves.
The Electromagnetic Spectrum
Has lowest frequency on the electromagnetic spectrum and has longest wavelength
Radio Waves
A model of light that explains why light carries energy, reflects, refracts, and can be absorbed or transmitted similarly to a mechanical wave.
Light Wave
Has higher frequency than radio waves and has a slightly shorter wavelength
(FOOD)
Microwaves
The amount of energy light waves carry to an area in a certain amount of time.
Light Intensity
A disturbance that carries energy, but not matter, from one place to another
Wave
A wave in which particles of matter move back and forth
Mechanical Wave
The matter that a mechanical wave travels through
Medium
A representation of a situation which makes important aspects easy to see
Model
A wave made of a single disturbance that does not repeat
Wave Pulse
One complete motion of the repeating pattern of a wave
Wave Cycle
A wave in which the matter moves in a pattern parallel to the direction that the wave travels
Longitudinal Wave
A wave in which the matter moves in a pattern perpendicular to the direction that waves travel
Transverse Wave
A wave in which the matter moves in a circular pattern that is sometimes parallel and sometimes perpendicular to the direction that the wave travels
Surface Wave
The size of a disturbance of a wave causes in its medium
AMPLITUDE
The number of wave cycles that pass a certain point in a given period of time; often expressed in wave cycles per second, or hertz
Frequency
The distance between the start of one wave cycle and the start of the next cycle
Wavelength
Close to the visible light part of the electromagnetic spectrum but NOT as intense.
Infrared Waves
Waves that are emitted by the sun and are absorbed by Earth’s atmosphere
Ultraviolet Waves (UV Waves)
WILDCARD: DOUBLE POINTS!
What is the meaning of life? Name all four.
1) Treat yourself kindly
2) Treat others kindly
3) Treat every day like a new day
4) Toes (thank you, Townes!)
Dangerous waves that are given off in the reactors of nuclear power plants
Gamma Rays
High frequency waves that are frequently used to take images of bones and teeth
X Rays
