How does the speed of sound relate to temperature elasticity and density?

The speed of any mechanical wave depends on the density of the medium. Since solids are the densest, the speed of sound is minimum in solids. It is the maximum in gases, since the medium is the least densest.

Explain how temperature affects the speed of sound?

Speed of sound depends on the density of the medium.

As temperature increases density decreases due to expansion in the volume. Hence speed of sound gets affected by the change in temperature.

Speed of sound is directly proportional to the square root of the temperature of the medium.

What it is the perception of the highness or lowness of sounds?

The perception of the highness or lowness of sounds is determined by their frequency. High-pitched sounds have higher frequencies, while low-pitched sounds have lower frequencies. This perception is a result of how our ears and brain interpret the vibrations of sound waves.

What moves faster light or speed waves?

matter waves as waves travel faster.. however you must know that we assume this condition to balance the Kinetic energy and energy of a photon according to plank's quantum theory and have no experimental proof about it :)

What is the speed of sound throw solid liquid and gas?

Gases:

The speed of sound depends upon the properties of the medium it is passing through. When we look at the properties of a gas, we see that only when molecules collide with each other can the condensations and rarefactions of a sound wave move about. So, it makes sense that the speed of sound has the same order of magnitude as the average molecular speed between collisions. In a gas, it is particularly important to know the temperature. This is because at lower temperatures, molecules collide more often, giving the sound wave more chances to move around rapidly. At freezing (0º Celcius), sound travels through air at 331 meters per second (about 740 mph). But, at 20ºC, room temperature, sound travels at 343 meters per second (767 mph).

Liquids:

Sound travels faster in liquids than in gases because molecules are more tightly packed. In fresh water, sound waves travel at 1,482 meters per second (about 3,315 mph). That's well over 4 times faster than in air! Several ocean-dwelling animals rely upon sound waves to communicate with other animals and to locate food and obstacles. The reason that they are able to effectively use this method of communication over long distances is that sound travels so much faster in water.

Solids:

Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air. The exact speed of sound in steel is 5,960 meters per second (13,332 mph)! But, this is only for the majority of solids. The speed of sound in all solids are not faster than in all liquids.

How does sound propagate in metals?

Same way it travels through air;

each molecule vibrates the one next to it

which then vibrates the one next to (the new it)

and so-on.

Why there are two holes in sonometer box?

The two holes in a sonometer box are used for passing the string or wire that holds the vibrating tuning fork or a weight. This allows the string to vibrate freely and produce a clear sound, which is crucial for accurate measurements in experiments involving sound waves.

How does the speed of sound in air compare with the speed of sound in water or steel?

The speed of sound in any medium is directly proportional to the density of that medium.

While I do not know the exact numeric answer to your question I can tell you that the speed of sound in those mediums would be ordered as follows (in ascending order)

# River Water # Sea Water # Steel

How does temp and humidity change the speed of sound?

Yes, it affects the density of air and thus the speed of sound in air.

What has the most impact on the speed of sound in seawater?

Any factor which alters the density of the sea water causes a variation in the velocity of sound in seawater. Basically, changes in temperature and salinity will result in changes in density. This can cause large changes in velocity.

For example, seawater in the carribean with a temperature of 20C and a salinity of 37ppt might result in a velocity of, say, 1530m/s, whereas seawater in the north sea with a temperature of 3C and a salinity of, say, 31ppt, would result in a velocity of, say, 1480m/s.

What is the speed of sound in air when the air has a temperature of 20degree celies?

That will not only depend on the temperature, but also on the exact composition of the air (such as, whether it is dry or humid), and possibly on the pressure. The typical speed of sound at 20 degrees C is approximately 343 meters/second.

What is the speed of sound as it passes through air?

The speed of sound is dependent on the temperature and not on the air pressure. At 20 degrees Celsius or 68 degrees Fahrenheit the speed of sound is 343 m/s or 1236.3 km/h or 1126.7 ft/s or 667.1 knots.

Scroll down to related links and look at "Speed of sound - temperature matters, not air pressure".

At room temperature (20°C, 68° F) the speed of sound is 343 meters per second, 767 miles per hour, or 0.213 miles per second.Sound waves must have matter and/or molecules to travel. Where there is no matter, such as in outer space, sound cannot travel.

At 20 degrees Celsius the sound travels in air 343.4 meters per second. That means in 1 second the sound travels 343.3 meters. In 2.912 milliseconds the sound travels 1 meter.
Well it is really dependent on the temperature of the air, but in this case we will assume the standard temperature ( 20 degrees C) it travels at 343 meters per second.
Through air, sound waves travel at 343 m/s

What strange thing happens to the Concorde when it goes faster than the speed of sound?

Sound waves are like ripples in a pond that radiate around the object. An aeroplane travelling at sub-sonic speed will be travelling behind the sound that it has emitted. When the aeroplane reaches the exact speed of sound, the sound it is producing will accompany it on its journey.

What is the speed of 100 KG person at the earth's equator?

Are you talking about the speed of rotation of the Earth's surface at the equator ?

Angularly, that would be 1 rotation/day, or roughly 1,038 miles per hour linearly.

The man's mass makes no difference. When a group of people all get together at the

equator, we don't see the heavy ones racing ahead or lagging behind the light ones.

Which of this speed are faster than the speed of a nerve messagespeed of electricityspeed of sound or speed of light?

The speed of light is faster than the speed of a nerve message, speed of electricity, and speed of sound. The speed of light in a vacuum is approximately 186,282 miles per second, while nerve impulses, electricity, and sound waves travel much slower.

How many Hz are in 740 kHz?

k\The k in kHz stands for "kilo" = 1000 so 740 kHz = 740,000 Hz. Simple!

What factors does the speed of sound not depend on?

The speed of sound does not depend on the amplitude of the sound wave or the frequency of the wave. It is primarily determined by the medium through which it travels, such as air, water, or solids. Additionally, the speed of sound is not influenced by the direction in which the sound is traveling.

What is the speed lower than the speed of sound called?

speeds lower than the speed of sound is known as the subsonic speed. speeds greater than the speed of sound is supersonic (mach 1) and speeds that are many times above the speed of sound (above mach 0) are known as hypersonic sounds.

Why bats can sense obstacles?

Yes, bats can sense obstacles. Bats use echolocation to hear and see at night. When the vibrations bounce back, a bat can sense if there are things in the way.

During a thunderstorm 3.4 s elapses between observing a lightning flash and hearing the resulting thunder Approximately how far away in kilometers and miles was the lightning flash?

As speed of light >> speed of sound, we can safely assume that the time taken for light to reach the observer is negligeable.

Taking speed of sound to be 340 ms-1 The distance can be found out by the formula

Distance = Speed * Time

= 340 * 3.4

= 1156 m
