What is sound waves?
A sound wave is the pattern of disturbance caused
by the movements of energy traveling through a
medium ( such as air, water or any other liquid or
solid matter) as it propagates away from the source
of the sound. Sound waves are created by the
objects vibration and produce preassure waves like a
What are sound waves called?
Sound wave is called longitudinal wave because it is
produced by compressions and rarefactions in the
air. The air particles vibrate parallel to the direction
What are sound waves used for?
Sound is an actual physical wave,we can manipulate
it to do something other than keep us entertained
during our work commute. It is also been used to
treat medical cinditions, clean, generate electricity
and make one of a kind artwork.
What is the importance of sound?
Sound is a crucial aspect of our everyday lives. Just
think about it - most of us communicate verbally, and
it's pretty hard to understand body language alone.
This makes sound the primary source of information.
What are the characteristics of a
Sound wave can be describe to five characteristics
and this are : wavelength, amplitude, timeperiod,
frequency and velocity or speed.
Whay frequency is sound waves?
The units of frequency are called hertz or Hz.
Humans with normal hearing can hear sounds
between 20hz and 20,000hz. Frequencies above
20,000hz are known as ultrasound.
What affects the speed of sound?
The speed of sound in a medium is determined by
combination of the medium's rigidity ( or
compressibility in gasses) and it's density. The more
rigid ( or less compressibile) the medium, the faster
the speed of the sound . The greater the density of a
medium, the slower the speed of the sound.
How fast can a sound travel?
On a standard day at a sea level static conditions,
the speed of a sound js about 760mph or 1000
Can sound travel in the water?
While sound moves at a much faster speed in the
water than in air, the distance that sound waves
travel is primarily dependent upon ocean
temperature and pressure.
Where is sound faster?
Sound travels fastest through solids. This is beacause
molecules in a solid medium are much closer
together than these in a liquid or gas allowing fact
,sound waves travel over 17 times faster through
steel than through air.
Why can't we hear underwater?
It's because the water is denser than air , since sound
waves travel faster underwater than in air , it is much
harder for us to detect where they are coming from .
Our bodies have something called bone conductivity.
Does wind carry sound?
Changing wind speeds above the ground cause
sound waves to bend toward or way on earth.
Can sound travel in empty space?
Sound can't be carried in the empty vacuum of space
cause sound waves need a medium to vibrate
through such as air and water.
Is sound louder in air or water?
Sound travels in water very fast compared with air
cause water particles are packed in more densely.
How does the sound made?
Sound is created by a vibrating objects, the
compression and expansion of the air on either side
of the vibrating membrane produces differences in
Reflection of sound, echo is a property of sound wave.
Once a echo occurs, it only meansbthat the sound
produced has bounced back . Refraction of sound,
refraction occurs when a wave travels from a dense to
a less dense media. Sound travels faster in cool air
than warm air because cool air is denser than warm
air. Diffraction of sound , diffraction occurs can be
easily observe by looking in the opening or size of the
obstacle, if the sound wave is bolcked,
That sound wave will look for a new path . If the
sound wave is blocked with a small opening , the
sound will pass through the opening and spread
again. Characteristics of sound . There are three
characteristics of sound pitch, loudness, and quality .
Pitch refers to higness and lowness of a sound.
Loudness of sound produced by vibrating object
depends in intensity of force that makes the object
The quality of sound ( or the timbre) sets the
difference of one tone from another . Speed of
Sound , the speed of sound depends on the medium
the wave pass through it's speed at sea level 344m/s
yet this may vary if affected by some factors.
Detecting sounds, when sound hits an object , it can
cause the object to vibrate
