why sound travels faster through rigid materials like steel than spongy material like rubber?

Answer 1

since sound travels usin mechanical waves and needs amaterial medium to propagate.......and since mechanical waves spread thru vibrations ...and since hard materials have their atoms packed closely....they need to vibrate with a smaller amplitude to pass on the wave....thus sound travels faster in a denser medium than a less dense one

Answer 2

The special property of matter is called sonorous due to which sound travel faster in still than rubber material.

Answer 3

The atoms in a rigid solid are more densely packed than in spongey rubber.

Therefore the atoms hit each other and transfer energy faster.

Answer 4

SOUND COMES TO US IN THE FORM OF A WAVE AND A WAVE RELIES ON THE MEDIA IT IS TRAVELING IN FOR IT'S VELOCITY. MOST HARD MATERIALS HAVE DENSELY PACKED MOLECULES SO THE WAVE OF SOUND HAS NO TROUBLE GETTING FROM ONE TO THE NEXT AND HENCE CAN TRAVEL SWIFTLY. SOFT THINGS HAVE THEIR MOLECULES LOOSELY PACKED AND THAT ACTS TO SLOW OR EVEN STOP THE WAVE FROM TRAVELING. PACK THE MOLECULES LOOSELY ENOUGH AND YOU GET INSULATION. EXCEPTIONS INCLUDE WATER, IT'S SOFT BUT THE MOLECULES ARE CLOSE AND SOUND TRAVELS QUICKLY - RIGID FOAM STRUCTURES CAN BE HARD BUT THE MOLECULES ARE PACKED FAR APART SO IT DEADENS SOUND.
