1. In the electromagnetic spectrum, which of the following
statements is true?
A) Wavelength and frequency are directly proportional
B) Wavelength and frequency are inversely proportional
C) Wavelength and amplitude are directly proportional
D) Wavelength and amplitude are inversely proportional
Correct Answer: B
Rationale: In the electromagnetic spectrum, wavelength and
frequency have an inverse relationship. As wavelength increases,
frequency decreases, and vice versa. This is a fundamental
1
,principle of wave physics expressed by the equation c = λν,
where c is the speed of light .
2. A nanometer (nm) is equivalent to:
A) 10⁻⁶ meters
B) 10⁻⁹ meters
C) 10⁻¹² meters
D) 10⁻³ meters
Correct Answer: B
Rationale: A nanometer is one-billionth of a meter, or 10⁻⁹
meters. Dental laser wavelengths range from approximately 655
nm (Diagnodent) to 10,600 nm (CO₂ lasers) .
3. The primary determinant of predicting tissue interaction of a
particular wavelength is:
A) Reflection
B) Scattering
2
,C) Absorption
D) Transmission
Correct Answer: C
Rationale: Absorption is the most important role in altering target
tissue. The wavelength of the laser must match the absorption
characteristics of the target chromophore to achieve the desired
therapeutic effect .
4. The diode laser's energy is delivered to the target tissue by
a(n):
A) Articulated arm
B) Hollow wave guide
C) Optic fiber
D) Mirror system
Correct Answer: C
Rationale: Diode lasers use a fiber-optic delivery system
composed of quartz or silica fibers. This flexible delivery system
3
, allows for precise contact and non-contact applications in various
dental procedures .
5. Which of the following characteristics could be used to
describe laser energy?
A) Monochromatic
B) Coherent
C) Collimated
D) All of the above
Correct Answer: D
Rationale: Laser light is unique compared to ordinary light
because it is monochromatic (single wavelength), coherent (waves
travel in phase), and collimated (beams travel parallel with
minimal divergence) .
6. Which of the following is a characteristic of ordinary light?
A) Single wavelength
B) Coherent
