LASER HAIR REMOVAL Exam Questions
With Correct Answers
LASER - answer✔Light amplification by the stimulated emission of radiation
Light consist of many wave lengths - answer✔Laser consist of just one
The FDA approved lasers for permanent hair reduction - answer✔In. 1997
When was the Ruby crystal laser invented - answer✔In 1960
The Ruby crystal uses what wavelength - answer✔694 nm
In 1960 the ruby crystal was invented and used for - answer✔Dermatology and ophthalmology
ELECTROMAGNETIC SPECTRUM of RADIATION - answer✔Visible and invisible light
The light we see belongs to what spectrum - answer✔ELECTROMAGNETIC SPECTRUM of
RADIATION
The spectrum of light is arranged by its frequency of its waves - answer✔Longest, lowest waves
to shortest highest waves. Radio waves are longest and gamma waves are shortest
Wavelength - answer✔Is the measurement between the distance of two consecutive peaks in a
wave ( peak or troughs )
Short wave length - answer✔High frequency
High intensity
High melanin absorption
Long wave length - answer✔Low frequency
Low intensity
Low melanin absorption
