Speed of Sound

The Concorde's cruising speed was over twice the speed of sound, around Mach 2 (more than 1,300 mph). The speed of sound at sea level is approximately 761 mph, so the Concorde flew significantly faster than the speed of sound.

As air warms up the sound wave will travel faster. The speed of sound in air depends upon the

temperature. The warmer the temp., the faster the sound moves.

As far as the pitch goes, I think it must depend on the instrument. My guitar goes flat as it gets

warm because the strings expand slightly and become longer. In a wind instrument, as the wave

travels faster in the instrument, the frequency will increase making the instrument go sharp. The

speed of sound is equal to frequency times wavelength, v = f L. The wavelength is determined by

the physical size of the instrument and is fixed. So, if velocity increases, and L is fixed,

frequency must increase to balance the equation. The higher the frequency, the higher the pitch. So,

I guess strings go flat, woodwinds, and brasses get sharp, and percussion depends on the type of

instrument, how the sound is physically produced, and what material the sound must travel through.

Light travels at 186,000 miles per second, which means you have to travel faster than that to break the light barrier. This feat is technically "impossible", since the faster you move, the more mass you have and the more mass you have, the more energy is required to move you, and by the time you reach the speed of light, you will need to have infinite energy. This doesn't apply to light particles, since they have no mass.

One reason may be that light doesn't involve actual movement of particles (atoms or molecules in this case). It takes some time to accelerate a particle.

It's about 340 m/s. Temperature, pressure, and humidity all have an effect on the exact speed.

For a liquid, we find that the speed of sound decreaseswith increasing density but increases with increasing bulk modulus. Increasing the dissolved solids will increase density, but also bulk modulus. In general, bulk modulus will increase "faster" with an increase in dissolved solids than density will increase. And this translates into a net increase in the speed of sound in water with increasing dissolved solids. Tap water has dissolved solids, so the speed of sound in tap water should be higher than it is in pure water at the same temperature and pressure.

It is impossible for an object to move faster than the speed of light in a vacuum. According to the theory of relativity, as an object accelerates towards the speed of light, its mass would approach infinity. This would require an infinite amount of energy, making it physically impossible.

Sound waves travel faster in water than in air because of the particle configuration. The particles in water are closer to each other compared to the particles in air. Since sound travels with one particle bumping into another and causing it to vibrate, sound waves travel faster in water.

No, a sneeze cannot travel faster than the speed of sound. The average speed of a sneeze is around 100 miles per hour, which is much slower than the speed of sound, which is about 767 miles per hour in dry air at room temperature.

Notice: The speed of sound changes with temperature and

a little bit with humidity − but not with air pressure (atmospheric pressure).

The words "sound pressure at sea level" are incorrect and misleading.

The temperature indication, however, is absolutely necessary. The speed of sound in air at 20 degrees Celsius (68 degrees Fahrenheit) is 343 metres per second. That is 1126.547 feet per second.

The answer is: No! In an ideal gas, which air can be considered, the speed of sound is given by:- c= √(γ(p/ρ)) where γ is the abiabatic index, p is the pressure and ρ is the density. and p= ρRT/M where R is the ideal gas constant, M is the Molar mass and T is the absolute temperature. From his equation, if temperature and mass are constant -, one can see that p is proportional to ρTherefore if atmospheric pressure is doubled so is the density Hence p/ ρ is constant. Therefore atmospheric pressure does not affect the speed of sound. However, increase in temperature will lead to an increase in speed. At high altitudes, the temperature is significantly lower, and hence the speed of sound is lower.

A hundred years ago twp people on lake Geneva in Switzerland measured the speed of sound in water. One made a signal and started ringing a bell under the water.The other one started a stopwatch and then held his head under the water until he heard the bell.

At or very near the surface it would take almost 34 hours.

The velocity is equal to the frequency times the wavelength.

Freq = 8Hz ("per second")

wavelength = 2 cm

2x8=16cm/s

Then multiply the velocity by the elapsed time...

16cm/s x 10sec.

(seconds cancel as units)

160cm

The speed of sound in standard temperature and pressure (STP) conditions is approximately 343 meters per second (m/s) in dry air at 20 degrees Celsius.

High pitched sounds, like all other sounds, travel in all directions in waves from their source. The direction they travel in can be affected by obstacles, reflections, and other factors, but they do not travel in a perfectly straight line.

Yes, sound typically travels at around 343 meters per second through air at sea level. This speed can vary depending on factors such as temperature and humidity.

The B-2's maximum speed is 628 mph while the speed of sound is 768 mph, so ii is subsonic (the B-2 cannot fly faster than sound).

If the speed of sound depended on frequency, distant music would sound distorted. Higher frequency sounds would travel faster than lower frequency sounds, causing a shift in the relative timing of different frequencies and resulting in a jumbled and unintelligible sound.

The speed of sound measured at sea level is 661.47 knots.

False. Newton's work did not involve the speed of light and sound. The concept of constant speed of light was later formulated by Einstein in his theory of relativity. The speed of sound can vary depending on the medium it travels through.

Sound waves can be slowed down by passing through mediums with high density or elasticity, such as solids. In these mediums, the particles are closely packed together, leading to frequent collisions that impede the speed of sound propagation. Additionally, temperature can also affect the speed of sound waves, with lower temperatures typically resulting in slower speeds.

The speed of sound varies when it travels through different mediums with different densities, temperatures, and pressures. In general, sound travels faster in solids and liquids compared to gases because the particles are closer together, allowing for more efficient propagation of sound waves. Additionally, the speed of sound increases with higher temperatures due to the faster average speed of the particles in the medium.
