One of it should be moisture of air. The more moist,the more sound particles are going to collide wtih. Analogy: if ure in a swimming pool,u will hear sounds louder than that in air. This is becuz ure surrounded by the water particles. As parties vibrate,it hits the nearby particles and.the cycle.carries on.
It is mainly the temperature of the air.
Speed of sound in air is c ≈ 331 + 0.6 × T.
T = Temperature in °C.
Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.
Temperature and air density.
The medium through which it is propagating. For exampl if the sound waves are travelling in air they will move slower than those travelling through a wall speed of sound in solids > speed of sound in liquids > speed of sound in gases
It is sound travelling through a dense medium, like iron, for example.
Travelling faster than the speed of sound causes a loud noise called the sonic boom.
The speed of sound through glass is 3962 metres per second, which is about 13000 feet per second. In normal air, sound travels at a speed of 343 meters per second and in water the speed is 1,433 metres per second. Sound travels at a speed of 5,000m per second or 11,160miles per hour through steel. The speed of sound is dependant upon the medium through which it is travelling and not on the loudness or pitch. For instance, sound travels much better through water than through air.
It means 8 times the speed of sound. Something travelling at 8 times the local speed of sound is said to be traveling at mach 8
The medium through which it is propagating. For exampl if the sound waves are travelling in air they will move slower than those travelling through a wall speed of sound in solids > speed of sound in liquids > speed of sound in gases
The speed of sound varies, depending on what material it goes through.
It is approx 4540 metres/second
Mach is the speed of an object expressed as a multiple of the speed of sound in the same medium. Thus, an object travelling at 686 metres per second through air, at sea level, is travelling at Mach 2 because sound would travel through it at 343 m/s. However, it the object was travelling under water at the same speed then it would be travelling at approx Mach 0.46 since sound travels at 1484 m/s through water.
It is sound travelling through a dense medium, like iron, for example.
Travelling faster than the speed of sound causes a loud noise called the sonic boom.
The Mach number of an object travelling through a fluid is its speed relative to the speed of sound travelling through the same medium. So an aircraft flying at Mach 1 at sea level would be travelling faster than an aircraft flying at Mach 1 at a high altitude (where the air is thinner and sound travels slower). An object travelling at Mach 2 is travelling twice as fast as an object travelling through the same fluid under the same conditions (temperature and pressure). BUT In common usage, Mach 1 is the speed of sound in air, at sea level and 20 deg C.
Yes. It depends on the refractive index of the medium through which the light is travelling.
Communication is at speed of sound. Signal attenuation. Noise of signal travelling through air.
Temperature affects the speed of sound through material by kinetic energy. The more molecules the higher temperatures will have more energy.
A: it is an incorrect question;Speed and Sound are different and cannot be compared.speed is the ratio between distance and time (how long does it take to go how far?)sound is a compression wave travelling through a medium
by causeing larger sound waves through objects
