Sound waves cannot travel through a vacuum. This means that if there is no air in the space between two objects, the sound waves will not be able to pass between them. This is because sound waves are a type of pressure wave that need a medium, like air, to travel through.

What are 3 things sound waves can travel through?
Sound waves can travel through a variety of different mediums, including air, water, and solids. Here are three examples of things that sound waves can travel through:
1. Air
Sound waves travel through the air as a result of pressure differences. When you speak or sing, your vocal cords create vibrations that cause pressure differences in the air around you. These pressure differences cause sound waves to travel through the air and reach your ears.
2. Water
Sound waves can travel through water because it is a denser medium than air. When you speak or sing underwater, the sound waves travel through the water and reach your ears.
3. Solids
Sound waves can also travel through solids, such as walls and floors. This is because solids are made up of tiny particles that vibrate when sound waves pass through them. These vibrations cause the solid to vibrate and create sound.
Why can’t sound waves travel through space?
Sound waves are created by vibrating objects, and need a medium to travel through in order to be heard. This is why you can’t hear a person’s voice from across a room, or even from the other side of a planet – the sound waves just don’t have enough time to travel that far.
The speed of sound is determined by the medium it’s travelling through. In air, it travels at around 700 miles per hour. However, in a vacuum (space), there is no medium for the sound waves to travel through, so they travel much more slowly. Scientists have calculated that the speed of sound in a vacuum is only around 1.5 miles per hour.
This is why you can’t hear a person’s voice from across a room, or even from the other side of a planet – the sound waves just don’t have enough time to travel that far.
There are some exceptions to this rule. For example, if you shout or clap your hands while in space, you will still hear the sound, but it will be a lot softer than it would be if you were in Earth’s atmosphere. This is because the sound waves are travelling through the air inside your spacecraft or space suit, and not through the vacuum of space.
Can sound pass through air?
Can sound pass through air?
It’s a question that has interested and perplexed people for centuries. The answer is yes, sound can travel through air, but there are a few things that need to be taken into account. The speed of sound, the type of air, and the weather can all have an impact on how well sound travels.
The speed of sound is determined by the air pressure and the temperature. The higher the pressure and the higher the temperature, the faster the sound travels. In general, sound travels at a speed of about 340 meters per second, or 770 miles per hour. However, the speed of sound can vary depending on the conditions.
The type of air also affects the speed of sound. In general, sound travels faster in moist air than in dry air. This is because the water molecules in moist air vibrate more quickly than the oxygen and nitrogen molecules in dry air.
The weather can also affect the speed of sound. In general, sound travels faster in calm weather than in windy weather. This is because the wind disturbs the air and makes it harder for the sound waves to travel.
Despite these variations, in most cases sound will travel more quickly through air than through water or other materials. This is why we can hear someone calling from a distance, even if they are not in sight.
What do sound waves travel through?
Sound waves are a type of energy that travels through the air and is used to communicate with others. They are created by vibrations that move through the air, and can be heard when they hit the ear drum.
Sound waves travel through the air, which is made up of molecules that are constantly in motion. The vibration of the sound wave creates pressure waves that move through the air. These pressure waves cause the air molecules to vibrate and move closer together, and then spread out again. This creates a vibration that can be heard by the human ear.
Sound waves can also travel through other materials, such as water and metal. In water, the sound waves cause the water molecules to vibrate and move closer together. This creates a vibration that can be heard by someone who is swimming or diving in the water. Sound waves can also travel through metal, which is why metal detectors are able to find metal objects.
What can sound waves travel through?
Can sound waves travel through air, water, or metal? The answer is yes – sound waves can travel through all three of these materials.
Sound waves are created when something vibrates, and these waves travel through the air, water, or metal until they reach our ears. We can hear sound because the waves cause our eardrums to vibrate, and this sends a signal to our brains that tells us what we are hearing.
Sound waves can travel through air, water, and metal because they are a type of energy. This energy can pass through different materials until it reaches our ears and allows us to hear sound.
Can sound waves travel through water?
Can sound waves travel through water? Yes, sound waves can travel through water. Sound waves are a type of energy that travels through the air and other mediums. When the sound waves reach the water, they will travel through the water until they hit an object and then bounce back. The sound waves will then continue traveling through the water until they are absorbed by something or they dissipate.

What can sound travel through?
Sound is a type of energy that travels through the air, or any other medium, as a vibration of pressure waves. These waves can travel through solids, liquids, and gases. The speed of sound through any medium is determined by its density and elasticity.
The human ear can only hear frequencies between 20 Hz and 20,000 Hz. Higher frequencies are known as ultrasound, and are used in medical diagnostics and therapy. Lower frequencies are known as infrasound, and are used to study the Earth’s atmosphere and oceanography.
Sound can be transmitted through many different types of materials, including air, water, metal, and plastic. It can be used to communicate over long distances, and can be used to detect objects and animals in the dark. Sound is also used in sonar and ultrasound imaging to create images of the inside of the body.
