4
8. Joules are used to measure energy delivered.
True
False
10) Watts (w) and milliwatts (mw, 1/ 1000th of a watt): units used to measure the
power capability
9. Watts and milliwatts are used to measure power.
True
False
11) Peak power: output: the maximum output of power, measured in milliwatts
and watts
12) Average power: amount of power actually delivered in a given period of time
13) Duty cycle: the amount of time the light is actually on during a given period
of time
14) LED-(Light Emitting Diode)- a solid state device that emits a narrow
bandwidth of light. A 660 nm LED will produce 94% of its light energy in between
658 and 662 nm.
10. LED stands for Light Emitting Diode.
True
False
15) Laser-(Light Amplification by Stimulated Emission of Radiation) A device that
produces a single wavelength of light energy that is coherent. A 632.8 nm laser
will produce 100% of its light energy in the 632.8 wavelength range.
11. A LASER is a device that produces a single coherent wavelength of light.
True
False
16) IPL-(Intense Pulse Light) High power light therapy devices that use an
intense flash bulb to produce a wide spectrum of light wavelengths and filters to
reject everything above a certain wavelength and below another wavelength to
let a bandwidth of light pass for biostimulation.
12. IPL stands for Intense Pulse Light
True
False
13 Cosmetic IPL devices use LEDs for their light source.
True
False
