100
high point of a wave
What is the crest?
100
waves transfer this
What is energy?
100
the bouncing back of a wave off a surface
What is reflection?
100
When two waves meet at the crest, it creates this kind of interference:
What is Constructive Interference?
200
low point of a wave
What is trough?
200
disturbance that transfers energy from one place to another without transferring matter
what are waves?
200
change in direction of a wave that occurs when a wave changes speed moving from one medium to another
What is refraction?
200
occurs when the crest of one wave interferes with the trough of another wave
What is destructive interference?
300
distance between two neighboring crests or troughs
What is wavelength?
300
In this kind of wave, the particles of the medium move up and down at right angles to the direction of motion of the wave
What is transverse?
300
sound waves are this type of wave (transverse or longitudinal)
What is longitudinal wave?
300
radio waves, light waves, microwaves, ultraviolet waves, and gamma waves are all this type of wave
what are electromagnetic waves
400
the height of a wave
What is amplitude?
400
In this kind of wave, the particles of the medium move back and forth in the direction of the wave.
What is longitudinal or compressional?
400
Mechanical waves (sound, water waves, seismic waves) need one of these, light waves do not
What is a medium?
400
This is the formula for wave speed
wave speed = wavelength x frequency
500
number of complete waves that pass a point in a given amount of time
What is frequency?
500
two parts of a longitudinal (comprassional) wave
What is compression and rarefaction?
500
occurs when waves that overlap combine, forming a new wave
What is interference?
500
This forms when a wave continues to resonate:
What is a Standing Wave
