Through which material does sound travel slowest?
sound will travel through air (gas), the slowest. Because the molecule sin the air are farther apart. Actually rubber it will travel through rubber the slowest. Air is second slowest then water and then granite was all I learned . Also Saltwater is faster then water becaus e there more salt so air goes through it faster.
Why do we see distant events before we hear them?
because light waves travel faster than sound waves, you see the light a lot sooner than you hear the sound.
Does sound travel through solids or gases faster?
Sound travels faster through solids because, molecules in solids are much closer together so this allows sound waves to travel faster.
What is the difference between light and sound?
The differences between light and sound are as follows:Light can be considered to be made of waves as well as particles. Sound is only a wave. It does not show particle nature.Light waves are electromagnetic waves while sound waves are mechanical waves.Light waves are transverse while sound waves are longitudinal.Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum.The speed of light in a medium is constant. The velocity of sound waves can change.In sound waves, the particles of the medium actually oscillate. In a light wave, the electric and magnetic vectors oscillate.Light waves can be polarized, but sound waves cannot.Light waves travel much faster than sound waves. The speed of light is a physical constant. Its value is exactly 299,792,458 metres per second in vacuuum. The speed of sound is 343 metres per second in dry air at 20°C.And finally, a simple one - you can see light while you can hear sound.
Is sound faster than the eyesight?
Light travels faster than sound. Light travels at nearly 300 million meters per second, whereas sound travels at 340.2 meters per second (both at sea level). Light is, thus, about three hundred thousand times faster than sound. (In miles per hour, the sound barrier is 761 mph)
How much pollution does a electromagnetic wave cause?
Electromagnetic waves only cause sound pollution because they are sound waves.
Do light and sound both move in waves?
Yes, both light and sound can be described as waves. Light waves are electromagnetic waves, while sound waves are mechanical waves. They both propagate through a medium, although light can also travel through a vacuum.
How much faster are light waves than sound waves?
About a million times faster
Why sound waves faster than light waves?
they aren't, they are much much slower.
Why sound waves change into electromagnetic waves in telephone?
Because an electric signal is much easier to transfer over long distances than a sound is.
Does light waves or sound waves travle faster?
Light travels much, much faster than sound. Light travels at 299792458 m/s while sound only goes 340.29 m/s.
Why do radio waves travel faster than the sound wave?
Radio waves are just low frequency light waves. They travel at the speed of light, much faster than sound waves which are just changes in pressure traveling in waves
About how much faster then sound are eletromacntic waves?
about 874,000 times as fast
Through which material does sound travel slowest?

Does sound travel through solids or gases faster?
Sound travels faster through solids because, molecules in solids are much closer together so this allows sound waves to travel faster.
What is different between electromagnetic and matter waves?
Electromagnetic waves are very much different from the matter waves and in many ways. a) Speed of matter waves is very much less than the speed of electromagnetic waves. b) Matter waves cannot be radiated in empty space unlike electromagnetic waves. c) Matter waves are just associated with the particle, not emitted by it Matter waves have smaller wave lengths than electromagnetic waves
