Q466
Propagation of sound can be visualised as propagation of ________ variations in the medium
A.
Elasticity
B.
Viscosity
C.
Density
AnswerD.
Porosity
Answer: Option C
Solution
Answer: Option C
Solution:
Pressure is related to the number of particles of the medium in a given volume. More density of the particles in the medium gives more pressure and vice-versa. Thus, propagation of sound may be visualised as propagation of pressure variations or density variations in the medium.
