ELECTROLYSIS IBEC & LASER STATE
BOARD TEST EXAM QUESTIONS AND
CORRECT ANSWERS.
1. In Galvanic electrolysis, the chemical reaction that occurs at the negative electrode
(cathode) produces:
A. Sodium hydroxide (Lye) and Hydrogen gas
B. Hydrochloric acid
C. Oxygen gas and Chlorine
D. Sulfuric acid
Answer: A
Conceptual Explanation: Galvanic electrolysis uses direct current to cause a chemical
decomposition of the salt and water in the follicle, producing sodium hydroxide (lye),
which destroys the germinative cells.
2. Which law of physics states that the amount of chemical action is proportional to the
quantity of electricity passed through the electrolytic cell?
A. Faraday’s Law
B. Joule’s Law
C. Ohm’s Law
,D. Grothus-Draper Law
Answer: A
Conceptual Explanation: Faraday’s Law describes the relationship between the amount of
electricity used and the amount of chemical substance produced in electrolysis.
3. The ‘Point Effect’ in thermolysis refers to the concentration of high-frequency heating at:
A. The top of the probe
B. The tip of the needle/probe
C. The middle of the probe
D. The surface of the skin
Answer: B
Conceptual Explanation: The Point Effect describes how the high-frequency current is
most intense at the tip of the probe, where the radius of curvature is smallest.
4. What is the primary chromophore targeted during laser hair removal?
A. Water
B. Hemoglobin
C. Protein
D. Melanin
Answer: D
, Conceptual Explanation: Laser hair removal relies on selective photothermolysis where
melanin in the hair shaft and follicle absorbs the light energy.
5. According to the Fitzpatrick Scale, a person who always burns and never tans is classified
as:
A. Type III
B. Type II
C. Type I
D. Type IV
Answer: C
Conceptual Explanation: Fitzpatrick Type I skin is characterized by very fair skin,
blue/green eyes, and hair that always burns and never tans.
6. The time it takes for a target to dissipate 50% of the heat absorbed is known as:
A. Pulse Duration
B. Wavelength
C. Thermal Relaxation Time (TRT)
D. Fluence
Answer: C
