Types of Waves
What is a disturbance that propagates through a material medium or space?
A Wave
What is period and time is measured in?
Seconds (s)
What is a Wavelength?
The shortest distance between two points that are “in phase”
What is a Reflection?
A sudden change in direction of propagation of a wave
Air, paper, & water can be an example of which wave characteristic?
A medium
What is wave that is not capable of transmitting its energy through a vacuum?
Mechanical Wave
What is wavelength usually measured in?
Meters (m)
What is the distance a wave travels in a given amount of time?
The Wave Speed
What is a Compression?
A region in a longitudinal wave where the particles are closest together
Pushing a person in a swing is an example of what?
Resonance
What is the displacement of the particles of the medium is perpendicular to The direction of wave propagation?
A Transverse Wave
What units represent the wave’s speed?
Meters/Seconds (m/s)
What is the number of complete vibrations per unit time?
The Frequency
What is a Rarefaction?
A region in a longitudinal wave where the particles are farthest apart?
An echo is an example of which property?
A Reflection
What is the displacement of the particles of the medium is Parallel to the direction of wave propagation?
A Longitudinal Wave
What units is amplitude is measured in?
Meters (m)
What is any substance through which a wave can travel?
A medium
What is a Refraction?
The change in direction of a wave passing from one medium to another
Waves traveling faster in deep water than in shallow is an example of what?
A Refraction
What is a Periodic Wave?
A wave with a repeating continuous pattern which determines its wavelength and frequency
The units of frequency
Hertz
What is an Amplitude?
The maximum displacement of a particle of the medium from the rest or equilibrium position
Where is the Crest and the Trough on a wave?
The crest is the highest point on a wave and the trough is the lowest point on a wave
The change in pitch of a police siren is an example of what?
A Dopper Effect
