Term
 Crest
Definition
 Peak of a transverse wave
Term
 Trough
Definition
 Lowest point of a transverse wave
Term
 Compression
Definition
 The points in a longitudinal wave where all the particles are bunched together. (high pressure)
Term
 Rarefaction
Definition
 The points in a longitudinal wave where all the particles are far apart (low pressure)
Term
 Longitudinal wave
Definition
 A wave that involves oscillations that occur parallel to the direction of the energy transfer
Term
 Transverse wave
Definition
 A wave that involves oscillations that occur perpendicular to the direction of the energy transfer
Term
 The Principal of Superposition
Definition
 When two waves of the same type meet, the resulting disturbance at any point and at any time is simply the vector sum of the resulting disturbances that would have occurred of the individual waves
Term
 Destructive Interference
Definition
 A situation that occurs when two identical waves meet at a point and are out phase by 180 degrees resulting in a wave of zero amplitude
Term
 Constructive Interference
Definition
 A situation that occurs when two identical waves meet at a point and are exactly in phase resulting in a wave that has twice the amplitude of either of the original waves
Term
 Wavefront
Definition
 A surface at right angles to the direction of a wave consisting of waves in phase
Term
 Wavelength
Definition
 Denoted by landa, this is the shortest distance (m) between two points that are in phase with one another
Term
 Wave speed
Definition
 The speed at which the wave pattern passes a stationary observer
Term
 Intensity of a wave
Definition
 The power per unit of area that is received by the observer
Term
 Traveling waves
Definition
 Progressive waves that transfer energy. This transfer is achieved by the oscillations of the medium through which the wave travels
Term
 Reflection at a boundary
Definition
 The situation that occurs when a wave is reflected at the boundary of two media resulting in the wave staying in its original position
Term
 Refraction at a boundary
Definition
 The situation that occurs when a wave is transmitted across the boundary between two media and subsequently moves from one medium into the other
