combination
which ray has the longest wavelength
infrared
which electrotherapy treatment can cause sebum to be broken down or blackheads to be liquefied, as in deep pore cleansing
discrustation
which type of light can create blue or cool tones
fluorescent
the effect that is created when an electric current travels through a water based solution in order to produce relaxing or stimulating results is known as
electrochemical
what temporary effect will a negative pole produce when applying galvanic current during an electrotherapy treatment?
increase blood flow

UV
during scalp and facial massage, faraday current is used to chiefly to cause _____ contractions
muscle
what uses a negative pole or electrode to force negatively charged solutions into the skin without breaking the skin
anaphoresis
the more frequently used application of the faradic current, in which a cosmetologist usually wears a wrist band with a moistened electrode, is known as the ____ method
indirect
the four types of currents used in electrotherapy are galvanic, faradic, sinusoidal and ______
tesla
slightly separating the electrode from the skin with a towel will produce a mild, stimulating sensation while using high frequency current
true or false
true
the application of special currents ( or modalities) that have a variety of effects on the skin is called
electrotherapy
bacteria that cause skin infections can be killed by what kind of light
UV
what introduces water soluble treatment products into the skin
ionphoresis
what types of light carries the most energy
UV
which type of current is an alternating current with a mechanical effect to help produce a muscle contractions
sinusoidal
when using UV rays make sure you and your Client wear
protective goggles
the direct current used in electrotherapy treatment is
galvanic
a current conductor used to direct the current from the appliance to the clients skin is called a
electrode
softening tissue is not a temporary effect of the positive pole of galvanic current
true or false
true
the chemical breakdown of the skin caused by intense heat is called
pyrolysis
the three methods for using Tesla current are direct application, indirect application and
general electrification
LED is an acronym which stands for what
light emitting electrode
the minimum distance an infrared light must bee placed from the clients face during a facial is ____ inches
30
when using galvanic current on clients in a salon what precaution must a cosmetologist take in order to prevent injury to the client?
not on broken capillaries
radiation, _______ and conduction are ways from heat to be transferred from one object to another
convection
the wavelengths that produce the longest waves of the visible spectrum are
red
treatment with light rays or waves is called
light therapy
electric current in a conductor causes heat by
increasing resistance in the line
if the client is holding the active electrode while the cosmetologist manually stimulates the area being treated what method of Tesla current is being used
indirect
when testing electrodes for polarity, the negative electrode will create
smaller bubbles
