How does density affect speed of sound?
Density describes the mass of a substance per volume. A substance that is more dense per volume has more mass per volume. Usually, larger molecules have more mass. If a material is more dense because its molecules are larger, it will transmit sound slower.
What is the relation between density and speed?
The relationships between speed and density are not difficult to observe in the real world, while the effects of speed and density on flow are not quite as apparent. Because flow is the product of speed and density, the flow is equal to zero when one or both of these terms is zero.
Is speed of sound proportional to density?
The speed of sound is proportional to the bulk modulus and inversely proportional to the density of the material.
Does the kind of medium affect the speed of sound?
The speed of sound in a medium is determined by a combination of the medium’s rigidity (or compressibility in gases) and its density. The more rigid (or less compressible) the medium, the faster the speed of sound. The greater the density of a medium, the slower the speed of sound.
What happens to the speed of sound in a medium if the temperature of the medium increases?
Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly.
What is the relationship between speed and sound?
The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength….Learning Objectives.

| Glass, Pyrex | 5640 |
| Lead | 1960 |
| Aluminum | 5120 |
When volume increases what happens to density?
When volume increases, density decreases.
Why is the speed of sound faster through a medium with a higher density?
A higher density leads to more elasticity in the medium and hence the ease by which compression and rarefaction can take place. This way the velocity of sound increases by increase in density.
How does the density of a medium affect the speed of a wave traveling through it?
Answer. Sound is a mechanical wave and travels by compression and rarefaction of the medium. Its velocity in an elastic medium is proportional to the square root of Tension in the medium. A higher density leads to more elasticity in the medium and hence the ease by which compression and rarefaction can take place.
What happens to the speed of sound when the temperature increases?
When the temperature increases the speed of sound also increase because particles move faster in higher temperature.
What is the relationship of types of medium with the speed of sound?
