Distance from midline to crest.
The number of oscillations in a second.
Time for one complete oscillation.
Energy can be transferred from a source to a receiver without the transfer of matter between the two points.
Wavelength/Period (Wavelength over Period)
Motion is at a 90 degree angle to the wave.
Motion is even with the wave.
Overlapping of waves.
When waves combine to form an amplified sound.
When waves cancel each other out.
An increase or decrease of waves as the source and observer move toward or away from each other.
V-Shaped wave due to the object moving faster than the waves.
A large amplitude wave caused by the sudden compression of the medium through which the wave moves.
(A fighter jet taking off)
Refers to how fast the disturbance is passed from particle to particle in a sound wave.
Distance/Time
Angle of incidence equals the angle of __________. The ___________ waves can interfere with incident waves, producing patterns of constructive and destructive interference.
The bending of waves when they enter a medium where their speed is different.
Generated by sound vibrations as they travel through a specific medium. This form of energy is also associated with disturbance of matter.
A form of mechanical energy.
A natural frequency of vibration determined by the physical parameters of the vibrating object.
The tendency of one object to force another adjoining or interconnected object into motion.
When two sinusoidal waves of equal amplitude and very nearly equal frequencies mix.
F = (fv1 + fv2)/2
The frequency of sounds.
The strength of the ears perception of a sound.
The characteristics of sound which allow the ear to distinguish sounds which have the same pitch and loudness.
Set into vibration at their natural frequency when a person hits, strikes, strums, plucks or somehow disturbs the object.
The ear is sensitive to ratios of frequencies (pitches) rather than to differences in establishing musical intervals.
Intervals which are perceived to be most consonant are composed of small integer ratios of frequency.
A method of defining periodic wave form S in terms of trigonometric function S.
+/- (Protons/Neutrons)
A variation of the Inverse Square Law
F = K (qv1 qv2/d^2)
Behaves as both conductor or insulator.
Material that acquires 0 resistance to the flow of charge; infinite conductivity.
Electrons are transferred by friction.
Polarization of electrons by being near (but no contact).
An energetic aura surrounding an object and extending through space.
1 Volt = 1 (joule/coulomb); Electrical potential energy.
A two terminal device which can maintain a fixed voltage.
A materials opposition to the flow of electric current.
Current flowing in one direction.
Electrons move first in one direction, then the other.
Current = Voltage/Resistance
Electrice circuit in which electrical devices are connected alone a single wire such that the same electric current exists in all of them.
A electric circuit in which electrical devices are connected in such a way that the same voltage acts across each on and any single one completes
the circuit independently of all the others.
Motion of charged particles; usually electrons.
Like ___ repel; Opposites attract.
Space around a magnet.
Clusters of aligned atoms.
Current carrying coil of wire.
At rest, it will interact with a static magnetic field. But if the _________ is moving, it becomes evident.
A wire with some resistance and voltage applied to it
Measures the amount of electric power.
Changes electricity to mechanical work.
Natural, organic compass.
Birds flying south for winter.
An electric field is created in any region of space in which a magnetic field is changing with time.
An electromagnetic inductiondevice that produces electric current by rotating a coil within a magnetic field.
Production of electric current.
Transfers electric power from one coil to another.
Current carrying loops in a coil touch each other.
The process by which a substance becomes magnetized by a magnetic field.
