Light can travel through a vacuum, such as outer space, whereas sound needs a medium, such as air, water, or solids to propagate. This is because light is an electromagnetic wave, while sound is a mechanical wave that needs particles to vibrate and transfer energy.

What happens to a sound wave if there are no particles to vibrate?
Without particles to vibrate, sound waves cannot propagate since they rely on the transfer of energy through particles. In a vacuum or empty space, there are no particles for sound waves to travel through, so they cannot be transmitted.
What speed do these waves travel through a vacuum?
Electromagnetic waves, such as light, travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second (186,282 miles per second). This speed is constant and represents the maximum speed at which information or energy can travel in the universe.
What material wont let light go through?
Opaque materials such as wood, metal, and thick plastics do not allow light to pass through them. These materials absorb or reflect light, preventing it from traveling through.
Objects that don't let light pass through them?
Objects that don't let light pass through them are called opaque. These objects absorb or reflect light, preventing it from passing through. Materials like wood, metal, and cardboard are examples of opaque objects.
Describe an experiment to demonstrate that sound wave require a material for propagation?
To demonstrate that sound waves require a material for propagation, one can set up two rooms with a speaker in one room and a microphone in the other. If there is air or another material between the two rooms, the microphone will pick up the sound waves. However, if the space between the rooms is in a vacuum, the microphone will not detect any sound, showing that sound waves need a medium to travel through.
Will sound travel faster or slower on moon than on earth?
Sound will travel slower on the moon than on Earth. This is because the moon's lack of atmosphere results in sound waves traveling at a slower pace due to the reduced medium through which they can propagate.
What happens to a sound wave if there are no particles to vibrate?
Without particles to vibrate, sound waves cannot propagate since they rely on the transfer of energy through particles. In a vacuum or empty space, there are no particles for sound waves to travel through, so they cannot be transmitted.
Why cant electrons escape copper wire?
It's kinda like a fire if there is nothing to burn the fire wont go there, so with electrons if there is nothing to travel in to (like a switch, a light bulb, a buzzer ect.) the electrons wont go there because they can't just travel through air like fire can't just travel through air.
If the light wont go through a material what is it called?
opaque

Can a subwoofer work without an amplifiers?
Yes a subwoofer can be plugged into a stereo without an amp but it wont sound good and wont hit anywhere near as hard as if you had it runnin through an amp... get an amp
Why are rockets good for space travel?
Rockets aren't necessarily good for space travel they are a necessity. You cant leave earth without a rocket... you wont be able to break through the atmosphere.
What material wont let light go through?
Opaque materials such as wood, metal, and thick plastics do not allow light to pass through them. These materials absorb or reflect light, preventing it from traveling through.
Do longitudinal waves travel through solids and liquids?
Confusing question. Try this - sound waves travel though solids and liquids (and gases), and electromagnetic ("radio") waves travel through a vacuum and gases well, les well through liquids such as water, and hardly at all though conducting solids such as metals.
Does magnetism travel thourgh stirafoam?
No, magnetism does not travel through Styrofoam because Styrofoam is non-magnetic and does not conduct magnetic fields. Materials that are not magnetic, like Styrofoam, will not allow magnetic fields to pass through them.
Can you travel to US with your UK travel document?
If that travel document is a passport then yes you can. Without passport it wont be possible
