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

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

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)

Imagine a superfast fish that is able to swim faster than the speed of sound in water. Would this fish produce a “sonic boom”? Use the concepts from this module to explain why flying bees buzz. If the handle of a tuning fork were to be handled firmly against a table, would the sound from the tuning fork change? If so, what would change? The strings of a harp have different length in order to produce different notes. However, given...

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. Consider a cubic meter of air and concentrate it on a N2 molecule that travels in the x direction at 330 m / s....

(a) Do you expect silver (Ag) to have a higher or lower speed of sound than gold (Au). Both elements are in the same column of the periodic table and have a fcc crystal structure. Why? (b) Choose the correct statements ( zero, one, or both may be correct) ---There is a maximum frequency above which no sound wave travels through silver ---There is a minimum frequency below which no sound wave travels through silver

Your cousin’s voice sound different over the telephone than it does in person. This is because telephones do not transmit frequencies over about 3000 Hz. Since 3000 Hz is well above the normal frequency of speech, why does eliminating these high frequencies change the sound of your cousin’s voice? Carefully provide the reasoning behind your answer.
