Sound

Sound waves are energy created by _________.

• stillness

• steadiness

• vibrations

• vividness

Sound can only travel through _________ (solid, liquid, gas).

• matter

• a vacuum

• a void

• outer space

Sound waves are _________waves because they must have a medium to travel through (solid, liquid, gas).

• transverse

• mechanical

Longitudinal waves, like sound, move through matter, from slowest to fastest, this way: _________________.

• solid, liquid, gas

• liquid, gas, solid

• gas, solid, liquid

• gas, liquid, solid.

Sound travels the fastest through solids, because its particles are ________ one another, allowing for a quicker transfer of energy.

• closer to

• further from

• a medium space from

Sound travels the slowest through gases (like air), because its particles are _________ one another, allowing for a slower transfer of energy.

• closer to

• a medium space from

• farther from

Sound can be _________ by matter.

• depicted, restricted, or absorbed

• reflected, refracted, or absorbed

• conflicted, restricted, or absorbed

When sound has a high frequency, it carries more energy, creating a ________ pitch.

• lower

• higher

When sound has a low frequency, it carries less energy, creating a ________ pitch.

• lower

• higher

When sound transfers to a different media (solid, liquid, gas), it will change its pitch due to a change in frequency or ________.

• matter

• energy
