4.2 Electricity Flashcards
type of light that can be broken into its individual wavelengths by a prism
combination
which ray has the longest wavelength
infrared
which electrotherapy treatment can cause sebum to be broken down or blackheads to be liquified
desincrustation
light that can create blue or cool tones
fluorescent
effect created when an electric current travels through a water based solution in order to produce relaxing result
electrochemical
what temporary effect will a negative poll produce when applying galvanic current
increase blood flow
which ray are also known as actinic rays
ultraviolet
during scalp and facial massage, faradic current is used to cause
muscle contractions
what uses a negative pole or electrode to force negatively charged solutions into skin
anaphoresis
the more frequently used application for the faradic current when cosmetologist wears wrist band
indirect method
four types of currents used in electrotherapy
galvanic, faradic, sinusoidal, and tesla
slightly separating the electrode from the skin with towel with produce a mild, stimulating sensation while using high frequency current
true
application of special currents that have a variety of effects on the skin is called
electrotherapy
bacteria that cause skin infections can be killed by
ultraviolet
what introduces water soluble treatment products into the skin
ionphoresis
light that carries most energy
ultraviolet
alternating current with a mechanical effect to help produce muscle contractions
sinusoidal
when using ultraviolet rays make sure you and your client wear
protective eyewear
direct current used in electrotherapy treatments
galvanic
current conductor used to direct the current from the appliance to clients skin
electrode
softening tissue is not a temporary effect of the positive pole of galvanic current
true
chemical breakdown of the skin caused by intense heat
pyrolysis
3 methods for using the tesla current are direct application, indirect application and
general electrification
LED is an acronym for
light emitting electrode
minimum distance an infrared light must be placed from the clients face
30 inches
when using a galvanic current on clients in a salon what precautions must a cosmetologist take
dont use in broken capillaries
ways heat is transferred from one object to another are radiation, conduction and
convection
wavelengths that produce the longest waves of the visible spectrum are
red
treatment with light rays or waves
light therapy
electric current in a conductor causes heat by
increasing resistance in that line
if the client is holding the electrode while the cosmetologists manually stimulates the area being tested on. what method is being used
indirect
when testing electrodes for polarity, the negative electrode will create
small bubbles
