Disturbances that transfer energy through space
The matter through which a wave travels
A wave that requires a medium through which to travel :: Disturbances in matter that carry energy
Mechanical Wave
– a wave cause by a disturbance in electric and magnetic fields and that does not require a medium; also called a light wave
Electromagnetic Wave
Wave that causes the particles of the medium to vibrate perpendicular to the direction the wave travels
Transverse wave
a wave that causes the particles of the medium to vibrate parallel to the direction the wave travels
Longitudinal wave
The highest point of a transverse wave
The lowest point of a transverse wave
The greatest distance that particles in a medium move from their normal position when a wave passes
The distance between two crests or two troughs
the time required for one full wavelength to pass a certain point
the number of vibrations per second
the speed at which a wave passes through a medium
Wave speed
an observed change in the frequency of a wave when the source or observer is moving
Doppler Effect
the bouncing back of a wave as it meets a surface or boundary
The bending of a wave as it oasses an edge or an opening
the combination of two or more waves that exist in the same place at the same time
any interference in which waves combine so that the resulting wave is bigger than the original waves
Constructive Interference
any interference in which waves combine so that the resulting wave is smaller than the largest of the original waves
Destructive Interference
the wave form caused by interference that appears not to move along the medium and that shows some regions fo no vibration and other regions of maximum vibration
Standing Wave
an electrical property of matter that creats a force between objects
Electric charge
a materical that transfers charge easily
a material that does not transfer charge easily
the force of attraction or repulsion between charged objects
electric force
the region around a charged object where it has an effect on other charged objects
electric field
the potential energy of a chraged object due to its postion in an electric field
Electrical potential energy
The difference in electrical potential energy between two places in an electric field
potential difference
a devise that is a source of electric current because of a potential difference, or voltage, between the terminals
the rate that electric charges move through a conductor
opposition to the flow of charges in a material
an electrical device connected so that i provides one or more complete paths for the movement of charges
Electric Circuit
a graphic representation of an electric circuit or apparatus, with standard symbols for the electrical devices
Schematic Diagram
Describes a circuit or portion of a circuit that provides a single conducting path
describes components in a circuit that are connected across common points, providing two or more separate conducting paths
the energy associated with the electrical charges, whether moving or at rest
Electrical energy
an electrical device containing a metal strip that melts when current in the circuit becomes too great
a device that protects a circuit from current overloads
Circuit Breaker
an area of a magnet where the magnetic force appears to be the strongest
Magnetic pole
a region where a magnetic force can be detected
magnetic field
a coil of current carrying wire that produces a magnetic field
a strong magnet created when an iron core is inserted into the center of a current-carrying solenoid
the productions of a current in a conducting circuit by a change in the strength, position, or orientation of an external magnetic field
Electromagnetic Induction
