The speed of sound in water is _____ than the speed of sound in air because _____. 

(a) Faster; water is much harder to compress 

(b) Faster; water is much more dense 

(c) Slower; water is much easier to compress 

(d) Slower; water is much less dense 

(e) Equal; the two fluids are at the same pressure

Solutions

Expert Solution

The speed of the sound is calculated from the Newton-Laplace equation. That is,

c = √K/ρ

 

Here, K is the bulk modulus and ρ is the density

 

As the speed of sound depends upon both the factors K and ρ. If a medium is not compressible at all that is incompressible means the speed of sound is infinite.

 

Therefore the speed of sound in water is faster than the speed of sound in air because water is much harder to compress.

 

Therefore, the correct option is (a).


The correct option is (a).

In this experiment, we have claimed to measure the speed of sound in air. To do this, we have used an audible frequency sweep. Why can we claim that the speed of sound will be the same over the bandwidth of the sweep? Is this assertion justified based on your results from experiment 2? Hint: Consider how sound (longitudinal pressure waves) propagate in a medium. (5 pts)

a) Kinetic theory. The speed of sound in the air is 330 m/s under standard conditions of temperature and pressure (273 K and 1 atm). Since the size of a molecule is much smaller than the average distance between the molecules, this number provides an estimate of the order of magnitude of the molecular media velocity.
