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.

Velocity of sound depends on?

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


How does solid affects the speed of sound?

The speed of sound varies, depending on what material it goes through.


What is the speed of sound travelling through glass?

It is approx 4540 metres/second


Is it Mach or times the speed of sound?

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.


What is a sound wave of 125hz and the speed of 5000 ms?

It is sound travelling through a dense medium, like iron, for example.


What happens if you are travelling faster than the speed of sound?

Travelling faster than the speed of sound causes a loud noise called the sonic boom.


What is Mach 1 and 2?

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.


Do speed of light depends on some factors as speed of sound depends on temperature?

Yes. It depends on the refractive index of the medium through which the light is travelling.


What are the disadvantage of ultrasonic wave communicaton?

Communication is at speed of sound. Signal attenuation. Noise of signal travelling through air.


How does temperature affect the speed of sound through a material?

Temperature affects the speed of sound through material by kinetic energy. The more molecules the higher temperatures will have more energy.


Is speed faster than sound?

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


How elasticity of a medium affects the speed at which sound travels?

by causeing larger sound waves through objects
