Miles per hour is a measure of speed, your question asks for an amount of time (I think).
Yes, sound can travel through metal strings. When a string is plucked, it creates vibrations that travel through the metal material and produce sound waves. The density and tension of the metal strings affect the speed and quality of the sound produced.
Sound would travel better through the metal railing because metal is a better conductor of sound than air. When the metal rod hits the railing, the vibrations are quickly transmitted through the metal and carry the sound along with it.
Yes, sound can travel through anything except nothingness like in space.
Sound can travel through air, water, solids (such as metal or wood), liquids, and gases.
Sound travels slower through stone compared to metal. This is because stone has a lower elasticity and density than metal, which causes the sound waves to propagate more slowly through it. Metal, with its high elasticity and density, allows sound waves to travel faster.
metal since it is solid
Sound travels faster through air. Though sound travels farther through solid objects (vibrations), it is faster when traveling through air waves.
Sound can travel through water, metal, rock and air, so the atmosphere isn't strictly needed for sound transmission.
Sound can travel effectively through air for several miles, depending on factors like temperature and humidity. In water, sound can travel much farther, up to hundreds of miles. In space, where there is no medium to carry sound waves, sound cannot travel at all.
Yes, sound can travel through lead, but it does so very poorly compared to other materials. Lead is a dense and heavy metal, which hinders the transmission of sound waves through it.
That's because sound is a compression wave. It needs a medium to travel through. The best mediums are dense, like metal and concrete. Liquids are okay. Gasses are the worst. Sound will not travel in space because there's no medium for sound to travel through.
Sound waves travel through a medium, such as air, water, or a solid material like metal or concrete. The medium acts as a carrier for the sound waves to propagate.
