ELECTROLYSIS IBEC & LASER STATE
BOARD PRACTICE EXAM QUESTIONS
AND CORRECT ANSWERS.
1. Which chemical is produced at the negative electrode (cathode) during the process of
Galvanic electrolysis?
A. Sodium Hydroxide (Lye)
B. Hydrochloric Acid
C. Oxygen Gas
D. Hydrogen Peroxide
Answer: A
Conceptual Explanation: In Galvanic electrolysis, the negative pole (cathode) produces
Sodium Hydroxide (Lye) through the decomposition of salt water in the tissues, which is
the chemical agent that destroys the hair follicle.
2. According to the Faraday equation, how many units of lye are produced if 0.5 milliamperes
of current flow for 20 seconds?
A. 5 units of lye
B. 10 units of lye
C. 15 units of lye
,D. 40 units of lye
Answer: B
Conceptual Explanation: The formula for units of lye is Intensity (mA) multiplied by Time
(seconds). 0.5 mA x 20 seconds = 10 units of lye.
3. The pattern of heat distribution in Thermolysis is known as a ‘pear-shaped’ or ‘drop-
shaped’ heating pattern. Which factor primarily determines the size of this pattern?
A. The intensity and duration of the High Frequency current
B. The moisture content of the skin
C. The length of the needle
D. The polarity of the active electrode
Answer: A
Conceptual Explanation: The heating pattern in thermolysis is determined by the
intensity and duration of the High Frequency current, also known as the ‘point effect’
where heat is most concentrated at the tip of the probe.
4. In the context of Laser Physics, what does the acronym LASER stand for?
A. Light Alteration by Systematic Energy Radiation
B. Light Amplification by Stimulated Emission of Radiation
C. Linear Amplification of Synchronized Energy Release
D. Low Absorption of Spontaneous Emission of Rays
, Answer: B
Conceptual Explanation: LASER is an acronym for Light Amplification by Stimulated
Emission of Radiation.
5. Which layer of the epidermis is responsible for the constant renewal of skin cells through
mitosis?
A. Stratum Corneum
B. Stratum Lucidum
C. Stratum Spinosum
D. Stratum Germinativum (Basale)
Answer: D
Conceptual Explanation: The Stratum Germinativum, also known as the basal layer,
contains the cells that actively divide via mitosis to create new skin cells.
6. Which laser wavelength is considered the ‘gold standard’ for hair removal on darker skin
types (Fitzpatrick IV-VI) due to its low melanin absorption?
A. 755 nm (Alexandrite)
B. 810 nm (Diode)
C. 694 nm (Ruby)
D. 1064 nm (Nd:YAG)
Answer: D
