SEISMIC WAVES.
Tranverse Waves.
it is produced by the string vibrating on the instrument when you strum it.
When you pluck the wire Longitudinal waves are produced.
Wavelength = velocity of sound in the medium / frequency Here velocity is not given. Let it be 330 m/s So required wavelength = 330/440 = 3/4 = 0.75 m
The sound waves produced by a whistle are at a higher frequency than that of a beaten drum, causing the sound registered by human ears to be at a "higher pitch". Dog whistles can only be heard by dogs because the sound waves produced are at such a high frequency, human ears cannot detect them.
When the tuning fork vibrates, it creates sound waves by compressing and rarefying the air around it. When the table tennis ball touches the vibrating prong, it is set into motion, swinging back and forth due to the alternating pressure from the sound waves. This motion illustrates how sound waves propagate through air, as the ball's movement mirrors the oscillation of air particles that carry the sound. Thus, the demonstration effectively shows the relationship between vibration and sound wave generation.
Vibrating objects.
Sound waves are produced by a moving or vibrating object. When an object vibrates, it causes the surrounding air molecules to also vibrate, creating a disturbance that propagates through the air in the form of sound waves.
When an object vibrates in the air, it creates sound waves. These sound waves travel through the air and reach our ears, allowing us to hear the sound produced by the vibrating object.
A vibrating object in a material medium produces sound waves. These waves are vibrations of particles in the medium that create a pattern of alternating high and low pressure regions, which our ears perceive as sound.
Not all vibrating objects produce sound. Sound is produced when a vibrating object creates compressional waves in a medium, such as air. If the vibrating object is not in contact with a medium that can carry sound, then no sound will be produced.
Sound waves are produced from vibrating air molecules. When an object vibrates, it causes the air molecules around it to also vibrate, creating changes in air pressure that travel as sound waves through the air.
The transfer of energy from a vibrating object in waves that travel through matter is known as sound. Sound waves are produced by the vibration of particles in a medium (such as air, water, or solids) and are characterized by properties such as frequency, amplitude, and wavelength.
To start an object vibrating to make a sound, you typically need to apply energy to the object. This energy causes the object to vibrate back and forth, creating sound waves that travel through the air. The frequency of the vibrations determines the pitch of the sound produced.
Basically, they begin with some vibrating object producing that sound.
Frequency waves are produced by a vibrating source, such as a sound wave produced by a vibrating object or an electromagnetic wave produced by an oscillating electric charge. The rate at which the source vibrates determines the frequency of the wave.
the air particles move a lot slower.
The source of energy for sound waves is typically mechanical energy, which comes from the vibrating object that produces the sound. When an object vibrates, it creates sound waves that travel through a medium like air, water, or solids. The energy from the vibrating object is transferred to the medium as the sound wave propagates.
