Cos Sci: Vocab Chpt 13 (Part 3)

Measurement of distance between two wavelengths.

• modalities

• wavelength

• waveform

• polarity

Process that turns the light from a medical lasers device into heat.

• light therapy

• nonconductor

• rectifier

• photothermolysis

The part of the electromagnetic spectrum that can be seen; makes up only 35% of natural sunlight

• microcurrent

• Tesla high-frequency current

• visible light spectrum

• volt

Unit that measures the resistance of an electric current.

• volt

• watt

• ohm

• photothermolysis

Also known as insulator; a material that does not transmit electricity.

• rectifier

• light therapy

• photothermolysis

• nonconductor

Invisible light that has a short wavelength (giving in higher energy), is less penetrating than visible light, causes chemical reactions to happen more quickly than visible light, produces less heat than visible light, kills germs.

• microcurrent

• ultraviolet light

• light therapy

• wavelength

Apparatus that changes alternating current (AC) to direct current (DC).

• rectifier

• modalities

• photothermolysis

• nonconductor

Also known as violet ray; thermal or heat-producing current with a high rate of oscillation or vibration that is commonly used for scalp and facial treatments.

• nonconductor

• light therapy

• visible spectrum of light

• Tesla high-frequency current

Negative pole or positive pole of an electric current.

• polarity

• modalities

• waveform

• wavelength

An extremely low level of electricity that mirrors the body's natural electrical impulses.

• microcurrent

• nonconductor

• light therapy
