Properties of Waves
Interactions of Waves
Seismic Waves
Key Terms
100
The material through which a wave travels
What is a medium
100
A measurement of frequency.
What is Hertz?
100
When an object or a wave hits a surface through which it cannot pass, it bounces back.
What is reflection?
100
The wave produced by an earthquake
What is seismic waves?
100
The bending of waves around the edge of a barrier.
What is diffraction?
200
The high part of this wave is called a crest and the low point is a trough
What is a transverse wave?
200
The distance from crest to crest or trough to trough on a wave.
What is wavelength?
200
The interaction of waves when they meet.
What is interference?
200
Huge surface waves on the ocean.
What is a tsunami?
200
The angle of incidence equals the angle of reflection.
What is the law of reflection?
300
A repeated back-and-forth or up-and-down motion.
What is a vibration
300
The maximum distance that the particles of a medium move away from the rest position.
What is amplitude?
300
Resonance
What is an increase in the amplitude of a vibration that occurs when external vibrations match an object/s natural frequency?
300
Seismograph
What is an instrument that records the ground movements caused by seismic waves?
300
The property of a wave that is a measure of the wave's energy.
What is amplitude?
400
A disturbance that transfers energy for place to place.
What is a wave?
400
The basic properties of waves.
What are amplitude, wavelength, frequency, and speed.
400
Points of zero amplitude on a standing wave.
What is a node?
400
A longitudinal seismic wave.
What is a P wave?
400
Two waves that combine to form a wave of zero amplitude.
What is destructive interference?
500
A wave that moves the medium parallel to the direction in which the waves travel.
What is longitudinal wave?
500
The mathematical formula relating speed, frequency and wavelength.
What is Speed = Wavelength x Frequency
500
The bending of waves due to speed.
What is resonance?
500
The way scientists tell how far away from them an earthquake occurred.
What is the time between the arrival of P waves and the arrival of S waves?
500
An echo is an example of this.
What is a reflected wave?
