Describe the physical properties of waves and wave pulses.
Waves transfer energy between two locations without transferring matter between those locations.
Waves transfer energy between two locations without transferring matter between those locations.
A wave pulse is a single disturbance that transfers energy without transferring matter between two locations.
Traveling waves are comprised of successive wave pulses.
13.1.A.4 Waves and wave pulses can propagate via different oscillation modes: transverse and longitudinal.
In a transverse wave the direction of the disturbance is perpendicular to the direction of propagation of the wave.
In a longitudinal wave, the direction of the disturbance is parallel to the propagation of the wave.
Water waves are an example of waves that involve a combination of both longitudinal and transverse motions. As a wave travels through the waver, the particles travel in clockwise circles. The radius of the circles decreases as the depth into the water increases
Mechanical waves or wave pulses require a medium within which to propagate. Electromagnetic waves or wave pulses do not require a medium within which to propagate.
The speed at which a wave or wave pulse propagates through a medium depends on the type of wave and the medium through which the wave travels.
Amplitude is the maximum displacement of a wave or wave pulse from its equilibrium position.
The energy carried by a wave increases with increasing amplitude.
