Does sound travel aster in steel or glass?
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.
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.
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
What happens if you are travelling faster than the speed of sound?
When travelling faster than the speed of sound (supersonic speed), a sonic boom is created. This is a loud noise produced when an object passes through the air at a speed greater than the speed of sound. It can be disruptive and can lead to regulations on supersonic flight over populated areas.
Will sound travel faster through Aluminium or glass?
Sound travels faster through aluminum than glass because aluminum has a higher speed of sound due to its higher stiffness and density compared to glass.
Can sound travel through glass and how can you tell?
Yes, sound can travel through glass. You can tell by tapping on the glass and listening for the sound vibrations to pass through it. Sound waves can propagate through the material, but the speed and transmission of sound may vary depending on the type and thickness of the glass.
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.
What happens to the speed of the light as it travels from the air through the glass and then through the water?
The light refracts due to the change in speed. The change in speed occurs because the light is travelling through a denser medium. So it will travel fastest through the air and slowest through the glass
What are the disadvantage of ultrasonic wave communicaton?
Communication is at speed of sound. Signal attenuation. Noise of signal travelling through air.
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
Will sound travel faster through water or a glass window?
window, because sound travels fastest through solids, liquids second, and gases last.
Term used for velocity of an aircraft at the speed of sound?
When an aircraft travels at the speed of sound, it is said to be travelling at Mach 1.
