DMS 100 Final Exam UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS
What did Pythagoras observe? - CORRECT ANSWER observed the relationship between
sound pitch and frequency
What did Aristotle develop? - CORRECT ANSWER The theory of sound propagation
What did Leonardo da Vinci develop? - CORRECT ANSWER thought to have developed the
idea that sound travels in waves and the angle of reflection is equal to the angle of incidence
What does the Law of Reflection state? - CORRECT ANSWER "when a ray of light reflects off
a surface, the angle of incidence is equal to the angel of reflection"
What did Galileo do? - CORRECT ANSWER started more modern studies of sound by
studying vibrations
What did Sir Isaac Newton study? - CORRECT ANSWER speech of sound in air and
demonstrated the 1st analytic determination of the speed of sound
What is Huygen's Principle? - CORRECT ANSWER "wavelets" combined to form a wave
front.
What is the doppler effect? - CORRECT ANSWER A source of wave motion itself moves the
frequency of the emitted wave changes
Who discovered the Doppler effect? - CORRECT ANSWER Christian Johann Doppler
What did the Curie Brother discover? - CORRECT ANSWER Piezoelectric effect
What is the piezoelectric effect - CORRECT ANSWER crystals expand and contract when
placed in an alternating electric field
, what is the reverse piexoelectric effect - CORRECT ANSWER permitted the same crystals to
create an electrical potential or voltage making the crystals useful as receivers and sources of sound
waves, which lead to the development of ultrasound transducers
What is A-mode - CORRECT ANSWER amplitude modulation
What is B-mode - CORRECT ANSWER brightness modulation
what is M-mode - CORRECT ANSWER motion modulation
Why is it important that our DMS program is accredited? - CORRECT ANSWER - follows a
