Term

Definition
Peak of a transverse wave 


Term

Definition
Lowest point of a transverse wave 


Term

Definition
The points in a longitudinal wave where all the particles are bunched together. (high pressure) 


Term

Definition
The points in a longitudinal wave where all the particles are far apart (low pressure) 


Term

Definition
A wave that involves oscillations that occur parallel to the direction of the energy transfer 


Term

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

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

Definition
A surface at right angles to the direction of a wave consisting of waves in phase 


Term

Definition
Denoted by landa, this is the shortest distance (m) between two points that are in phase with one another 


Term

Definition
The speed at which the wave pattern passes a stationary observer 


Term

Definition
The power per unit of area that is received by the observer 


Term

Definition
Progressive waves that transfer energy. This transfer is achieved by the oscillations of the medium through which the wave travels 


Term

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

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
