simple harmonic motion
term for oscillation due to a restorative force that is proportional to the displacement from a central, or equilibrium, position
term for the lowest point of displacement of a wave
The waveform generated by a harmonic oscillator is _____; that is, it is identical in form to the graph of the equation y = sin θ
term for a wave train in which the same wave form appears at regular intervals along the path of the train
term for the number of waves that pass a given point per unit time in any periodic wave train
term for the time required for a single wave to pass a given point
term for a wave train's linear advance per unit time
term for a peak of a wave
term for the distance from one crest to the next, or from one trough to the next, or from any point on a wave to the corresponding point on the next wave
one-dimensional wave
term for a wave that follows a straight line, such as one that moves along a rope
term for the boundary between water and air to which a wave is confined
two-dimensional wave
term for a wave that widens but does not deepen

term for a wave that travels outward in all directions away from the source
a water wave

term for the type of wave that is created when a stone is dropped into a still pond
term for a circle drawn through all points having the same displacement in the same circular wave
term for an arrow indicating the direction of wave motion

term for a wave that travels three-dimensionally outward from a source

term for the change in direction after two- or three-dimensional waves pass obliquely in to a region where they either speed up or slow down
term for the spreading out of a wave after it passes through a narrow opening
principle of superposition
the principle that states that when two or more waves are traveling simultaneously through the same point in a medium, the displacement of any particle at that point is the algebraic sum of the displacements that would be caused by the waves separately

term for the wave train produced by superposition of different wave trains
constructive interference
term for greater displacement as a result of superposition
