Electrostatics
Electrical charge is neither created nor destroyed, it is only transferred.
What is Conservation of charge?
The highness or lowness of a sound.
What is pitch?
The distance between successive crests, troughs, or identical parts of wave.
What is the wavelength?
Describes a sound that has a frequency too low to be heard by the human ear.
What is infrasonic sound?
The loud sound that results from the incidence of a shock wave.
What is sonic boom?
What is a conductor?
The power per square meter carried by a sound wave, measured in decibels.
What is intensity?
For a wave or vibration, the maximum displacement on either side on either side of the equilibrium position.
What is amplitude?
Describes a sound that has a frequency too high to be heard by the human ear.
What is ultrasonic sound?
What is a hertz?
A material that does not contain free charged particles and which charge does not easily flow.
What is an insulator?
The physiological sensation directly related to sound intensity or volume.
What is loudness?
A wave in which the medium vibrates perpendicularly to the direction in which the wave travels.
What is a transverse wave?
The persistence of sound, as in an echo, due to multiple reflections.
What is reverberation?
The number of vibrations per unit of time.
What is frequency?
The study of electric charge at rest.
What is electrostatics?
The lowest frequency of vibration in a musical tone.
What is fundamental frequency?
A wave in which the medium vibrates parallel to the direction in which the wave travels.
The bending of sound caused by a difference in wave speeds.
What is refraction?
A result of superposing different waves, often the same wavelength. Can cause reinforcement or cancellation of the wave.
What is interference?
When charges of an atom or molecule are aligned so that one side has a slight excess of positive charge and the other side has a slight excess of negative charge
What is electrically polarized?
A partial tone whose frequency is an integer multiple of the fundamental frequency.
What is a harmonic?
The shift in received frequency due to the motion of a vibrating source toward or away from a receiver/
When the frequency of forced vibrations on an object matches the object's natural frequency and increases the amplitude.
What is resonance?
The cone-shaped disturbance created by an object moving at supersonic speed through a fluid.
What is shock wave?
