Questions and CORRECT Answers
Acoustics - CORRECT ANSWER - Acoustics refers to the scientific study of sound waves
in terms of how it is generated and
transmitted.
Why do we study wave motions and oscillation in acoustics? - CORRECT ANSWER - We
study the properties of wave motion and oscillation in order to have a
precise understanding of sound waves and their characteristics.
What are the essential properties of sound source and sound medium? - CORRECT
ANSWER - Mass and Elasticity
Sound source and Sound Medium are (.....) of eachother - CORRECT ANSWER -
Independent
The frequency and period of is determined by the properties of? - CORRECT ANSWER -
The sound source
The speed of transmission is determined by the properties of? - CORRECT ANSWER -
The sound medium
How do sound waves propagate? - CORRECT ANSWER - When set into motion, air
molecules oscillate back and forth about their equilibrium
positions, causing adjacent air molecules to move closer together and air pressure to
increase (condensation) and then move further apart causing air pressure to decrease
(rarefaction). It is the disturbance which travels, not the individual air particles in the
medium. Sound waves propagate in a spherical, longitudinal fashion.
