Scientific notation of velocity of sound?
The velocity of sound in air at sea level at normal temperature and pressure is 3.4329 metres/second.
What is the function of a megaphone?
megaphones are a device that loud-ens sound to a distance.
What formula is Vfx λ?
It looks a little like V = f x λ, which to me means velocity = frequency multiplied by wavelength. For example, with sound, you could have a frequency of 100Hz and a wavelength of 3.4m giving a velocity of 340m/s. Alternatively you could rearrange the equation if the velocity is know but the frequency or wavelength isn't
What is the distance sound travels in one hour?
About 767 miles, depending on the temperature and density of the air.
What are the conditions necessary to hear echo?
The reflecting surface must be sufficiently smooth and shaped such that the sound is reflect back and not dispersed. Sound travels at approx 340 metres per second and the average human brain easily can distinguish sounds that are 1/2 second apart. That means the sound must travel at least 170 metres so that the reflecting surface must be half that distance away. While a greater distance will create a more distinctive echo, the strength of the returning sound fall off rapidly (at twice the square of the distance to the reflecting surface). In normal circumstances 170 metres (= approx 500 feet) is a good distance. A cave or convex reflecting surface will allow a greater distance.
What should be the weight of the person projected with velocity of sound in vacuum and travellig millions of kilometer of distance?
The force (weight) between the person and earth diminishes with distance. eg double the distance, quarter the force.
Why does the pitch of a sound change as the source of the sound that moves past you?
Decreasing velocity, and distance.
What is the difference between sound in water and sound in air?
Velocity (distance-time), Magnitude (volume) and Density (echo/harmonic) signatures differ.
When was Velocity of Sound created?
Velocity of Sound was created on 2002-10-08.
Why thickness varies in percussion instruments?
Thickness affects sound.
What is the approximate velocity of the sound in air?
the velocity of sound in the air is 300m/s
Write an experiment to find the velocity of sound?

How is an echo sounder used to determine the bathymetry of the ocean floor?
They send down a sound wave (whose velocity they know) and measure how much time it takes for it to return. Velocity=Distance/time Distance=Velocity*time They divide the distance by 2 (since the sonar wave has to return as well.) They make thousands of these measurements to make a map of the ocean floor based on these distances.
Is Sound listen greater in solids or in air?
Sound velocity is greatest in solids, and the solid with the highest velocity of sound is metallic Beryllium.
Give the effect of density on velocity of sound?
As density increases, the velocity of sound increases because there are more particles for the sound wave to travel through. Conversely, if the density decreases, the velocity of sound will also decrease because there are fewer particles for the sound wave to travel through.
The velocity of a sound wave travel though the air is approximately?
Velocity of sound in air is 324m/s.
How is wave velocity determined?
Wave velocity is determined by the medium through which the wave is traveling and the properties of the wave itself, such as frequency and wavelength. It can be calculated as the product of wavelength and frequency or by dividing the distance the wave travels by the time it takes to travel that distance. Additionally, the type of wave, such as sound or light, can also affect the velocity at which it travels through a medium.
