Sound comes from vibrations. These vibrations create sound waves which move through mediums such as air and water before reaching our ears.
Our ears vibrate in a similar way to the original source of the vibration, allowing us to hear many different sounds.
Dogs can hear sound at a higher frequency than humans, allowing them to hear noises that we can't.
Sound is used by many animals to detect danger, warning them of possible attacks before they happen.
Sound can't travel through a vacuum (an area empty of matter).
The speed of sound is around 767 miles per hour (1,230 kilometres per hour).
The loud noise you create by cracking a whip occurs because the tip is moving so fast it breaks the speed of sound!
When traveling through water, sound moves around four times faster than when it travels through air.
The scientific study of sound waves is known as acoustics.
Although music can be hard to define, it is often described as a pleasing or meaningful arrangement of sounds.
The sound of thunder is produced by rapidly heated air surrounding lightning which expands faster than the speed of sound.

Sound waves are mechanical waves that require a medium to travel through, such as air, water, or solids. They are characterized by their frequency (pitch), amplitude (loudness), and speed of propagation. Sound waves can be reflected, refracted, absorbed, or diffracted as they interact with different materials.

Does sound produce waves?
Yes, sound produces waves known as sound waves. These waves are vibrations that travel through a medium, such as air or water, and are detected by our ears as sound.
What are three facts about compressional waves?
Compressional waves are also known as longitudinal waves, where particles move back and forth in the same direction as the wave. These waves are characterized by the compression and rarefaction of the medium they travel through. Examples of compressional waves include sound waves and seismic waves.
Can sound waves be seen?
No, sound waves cannot be seen with the naked eye. Sound waves are vibrations in the air that are sensed by our ears, but they do not have a visual component like light waves.
Does a soft sound have tall waves?
No, a soft sound typically has low amplitude waves (shorter in height) compared to a loud sound that has high amplitude waves (taller in height). The amplitude of a sound wave is directly related to its volume or intensity.
What are examples of longitudinal waves?
Examples of longitudinal waves include sound waves, seismic waves, and sound waves in solids (such as ultrasound waves). These waves propagate by compressing and rarefying the medium in the direction of wave motion.
What sound waves do?
Sound waves carry sound
Does sound produce waves?

Sound waves are examples of what?
sound waves are a example of mechanical waves

What does sound travel on?
Waves; sound waves.
How do vibrations produce sound waves?
sound waves dont produce vibrations, vibrations are sound waves.
What can you hear but can not see?
Sound waves
Define the term sound waves?
Waves of sound.
What is the objective of travel faster radio waves or sound waves?
sound waves
What kind of wave are sound waves?
Sound waves are longitudinal waves; they travel from side to side, not up and down like transverse waves.
Can sound waves be seen?
No, sound waves cannot be seen with the naked eye. Sound waves are vibrations in the air that are sensed by our ears, but they do not have a visual component like light waves.
When were sound waves made?
Sound waves are made whenever and wherever there is a sound.
