When a sound wave moves past a point in air what happens to the density of air at this point?
The density of air increases and then decreases as the sound wave passes.
What does a velometer measure?
Air velocity in ventilation systems
What is the speed of the wave if the frequency of Hz and the wavelenghth of 87 m?
The velocity of a traveling wave is dependent on the composition of the conducting medium. Not directly on frequency. Though many conductive media are frequency dispersive - they conduct different frequencies at different speeds. Thus we get our rainbow. In air, sound travels about 300m/sec. But in water, about three times that velocity. And in metals, about ten times that velocity.
What force is it when a big truck passes you on the highway?
The shock wave all objects make as they push air out of their way to move. A truck has a substantial bow shock you can feel. The air currents you produce as you pass a desk and a piece of paper moves.
Is terminal velocity a type of friction?
No. Terminal velocity is a particular kind of velocity and friction is a particular kind of force. The terminal velocity of a falling object is the maximum velocity it can have because air resistance prevents it from going any faster. And air resistance is a type of friction. So terminal velocity is due to a type of friction.
The velocity of a sound wave travel though the air is approximately?
Velocity of sound in air is 324m/s.
When the temperature of the air is 25 degrees the velocity of a sound wave traveling through the air is?
when the temperature of the air is 25 degrees Celsius, the velocity of a sound wave traveling through the air is approx.
What happens to the direction of the wave as it passes into the air?
The direction of the wave will eventually change to where the wind is blowing.
What is sound wave velocity?
Sound waves are longitudinal waves in air. Velocity of sound waves in air at NTP = 332 m/s.
What is a refracted wave?
It means that the wave changes direction when it passes from one medium to another - for example, from air to water, or from denser air to less dense air.
What is a refractive wave?
It means that the wave changes direction when it passes from one medium to another - for example, from air to water, or from denser air to less dense air.
When a sound wave moves past a point in air what happens to the density of air at this point?
The density of air increases and then decreases as the sound wave passes.
What is refraction of a wave?
It means that the wave changes direction when it passes from one medium to another - for example, from air to water, or from denser air to less dense air.
When a wave travelling in air enters into a waveguide The phase velocity will increase?
increases
When the tmperature of the air is 25 C the velocity of a sound wave traveling through the air is aproximately?
340m/s
When the temperature of the air is 25centermeter the velocity of a sound waves traveling?
rarefactionoccurs only in-wave
Why would a wave bend when it passes from air into water?
The speed of light slows in water.
