200
halved
If the frequency of a wave is doubled and if the speed remains constant, its wavelength is ____.
200
the highest point above equilibrium
What is a crest?
200
True
The SI unit for frequency is hertz.
200
frequency
The number of cycles of a periodic wave occurring per unit time is defined as a wave's ____.
300

What is a pendulum?
300
200
A period of 0.005 seconds would be equivalent to a frequency of ____ Hz.
300
pulse
A single disturbance that moves from point to point through a medium is called a ___.
300
the lowest point below the equilibrium
What is a trough?
300
distance from the equilibrium position to a crest or a trough
What is amplitude ?
400
moves ground in a circle, causes most shaking.
What are Rayleigh waves?
400
vibration about an equilibrium position in which a restoring force is proportional to the displacement from the equilibrium.
What is a simple harmonic motion?
400
spring force always pushes or pulls the mass towards its original equilibrium position.
What is hooke's law?
400
frequency
As a wave passes across a boundary into a new medium, which characteristic of the wave would NOT change?
400
True
The number of waves generated per second by a source is called the frequency of the source.
500
partly reflected and partly transmitted.
When a pulse reaches a boundary between two different media, it will be____.
500
longitudinal
If the particles of the medium are vibrating to and fro in the same direction of energy transport, then the wave is a ____ wave.
500
remains the same
As a pulse travels though a uniform medium, the speed of the pulse ____.
500
bending of light as it passes from medium to another.
What is Refraction?
500
False
Doubling the frequency of a wave source (without altering the medium) doubles the speed of the waves.
