Q

ELECTRICITY?

A

Form of energy that when in motion exhibits magnetic, chemical, or thermal effects; a flow of electrons.

18
Q

ELECTRODE?

A

Applicator for directing the electric current from the machine to the clients skin.

19
Q

ELECTROMAGNETIC RADIATION?

A

Also called radiant energy because it carries, or radiates energy through space on waves.

20
Q

FUSE?

A

Special devise that prevents excessive vurrent from passing through a circuit.

21
Q

GALVANIC CURRENT?

A

Constant and direct current (DC), having a positive and negative pole and producing chemical changes when it passes through the tissues and fluids of the body.

22
Q

INACTIVE ELECTRODE?

A

Opposite pole from the active electrode.

23
Q

INFRARED RAYS?

A

Invisible rays that have longer wavelengths, penetrate deeper, and produce more heat that visible light.

24
Q

INSULATOR or NONCONDUCTOR?

A

Substance that does not easily transmit electricity.

25
Q

IONTOPHORESIS?

A

Process of introducing water-soluble products into the skin with the use of electric current, such as the use of the positive and negative poles of a galvanic machine.

26
Q

KILOWATT?

A

1000 watts.

27
Q

MIILIAMPERE?

A

One thousandth of an ampere?

28
Q

MODALITIES?

A

Currents used in electrical facial and scalp treatments.

29
Q

OHM?

A

Unit that measures the resistance of an electric current.

30
Q

POLARITY?

A

Negative or positive pole of an electric current.

31
Q

RECTIFIER?

A

Apparatus that converts alternating current to direct current.

32
Q

RED LIGHT?

A

Therapeutic light used on dry skin in combination with oils and creams;penetrates the deepest and produces the most heat.

33
Q

TESLA HIGH FREQUENCY CURRENT?

A

Thermal or heat-producing current with a high rate of oscillation or vibration; also called violet ray.

34
Q

ULTRAVIOLET (UV) RAYS?

A

Invisible rays that have short wavelengths, are the least-penetrating rays, produce chemical effects, and kill germs; also called cold rays or actinic rays.

35
Q

VISIBLE LIGHT?

A

the primary source of light used in facial and scalp treatments. all the light we can see.

36
Q

VOLT?

A

unit that measures the pressure or force that pushes the flow of electrons forward through a conductor.

37
Q

WALL PLATE?

A

Instrument that plugs into an ordinary wall outlet and produces various types of electric currents that are used for facial and scalp treatments.

38
Q

WATT?

A

Measurement of how much electric energy is being used in one second.

39
Q

WAVELENGTH?

A

Distance between successive peaks of electromagnetic waves.

40
Q

WHITE LIGHT?

A

Referred to as combination light because it is a combination of all visible rays of the spectrum.
