How does sound travel?

How does sound travel?

Multiple Select

Choose all that apply to sound.

• Moves by vibrations

• Must have a medium to transfer sound energy

• Closeness of particles determine the speed of sound.

• The closer particles are the faster the vibrations get passed on.

Multiple Choice

Sound travels in solids best because;

• solids have a higher density

• particles of matter are closer together

• particles of matter don't have to travel far to pass on the vibrations

• all of these choices

Multiple Choice

Liquids as a medium;

• are less dense than solids

• are more dense than gases

• transfer vibrations faster than gases

• all of these

Multiple Choice

Gases are the worst medium for transferring sounds because;

• it is more dense than solids and liquids

• gas particles are too far apart they don't transfer vibrations

• have to move farther distances to pass on vibrations

• they aren't made

  of matter

Multiple Choice

Which medium is best for sound to travel through?

• liquids

• gases

• solids

Multiple Choice

Temperature affects the transfer of sound by;

• speeding up the particles of matter

• allowing vibrations to move faster through the heated medium

• affect the speed of sound transfer

• all of these

Multiple Choice

Multiple Select

Check all that apply in order for an echo to occur;

• sound waves have to be reflected off of an object
