Parts of Waves
How waves Interact with Matter
Characteristics of Waves
100
Energy
What is the ability to make something happen or the ability to do work?
100
Mechanical waves
What is waves that require a medium through which to travel?
100
Rest Position
What is the position where the wave is at rest, halfway between the crest and the trough?
100
Matter
What is anything that has mass and volume?
100
Amplitude
What is the maximum distance the particles move away from their rest positions?
200
Transfer of Energy
What is caused when molecules move the energy of motion to other molecules then they return to the state of rest?
200
Longitudinal/Compressional waves
What is waves that move the medium parallel (II) to the direction in which the energy travel?
200
Compression
What is the part of a longitudinal wave where the particles of the medium are close together?
200
Transmit
What is to send forward as a recipient or destination?
200
Decibles
What is the unit used to measure the intensity (loudness) of sound?
300
Wave
What is the disturbance caused by a vibration that transfers energy from place to place?
300
Sound wave
What is a disturbance that passes through a medium as a longitudinal/compressional wave?
300
Rarefraction
What is the part of a longitudinal wave where the particles of the medium are far apart?
300
Absorption
What is to take in;The waves energy is taken in and converted into some other form of energy, such as heat?
300
Lumens
What is the unit used to measure the intensity (brightness) of light?
400
Vibration
What is a repeated up and down, or back and fourth motion?
400
Electromagnetic wave
What is a wave that originates from the sun and travel through space?
400
Crest
What is the highest part of a transverse wave?
400
Reflection
What is the bouncing back of a wave when it hits a surface which it cannot pass?
400
Wavelength
What is the distance between two corresponding parts of a wave (mm)?
500
Source
What is the origin of the wave, what starts it?
500
Transverse waves
What is waves that move the medium in a direction perpendicular to the direction in which the energy travel?
500
Trough
What is the lowest part of a transverse wave?
500
Refraction
What is the bending of waves as they enter a different medium?
500
Frequency
What is the number of waves that pass a given point in a certain amount of time, usually one second?
