Sound

Sound Grab Bag

Top of a wave

What is the crest?

Bottom of a wave

What is the trough?

The point directly in the middle of a waves crest and trough

What is the rest position?

The distance between any two wave crests that are next to one

another.

What is a wavelength?

Distance from the

wave crest to the rest position

What is the amplitude

The number of vibrations a wave has in a given

time

What is frequency?

The perception of the frequency

of a sound as being high or

low

What is pitch?

The perception of a sound as being loud or

soft

What is amplitude?

When the wavelength of a wave decreases

the frequency does this.

What is decrease?

When frequency decreases this happens to the

pitch.

What is decrease?

Where sound originates or comes from

What is the source?

Sound leaves a source and is

carried through these

What are vibrations?

Sound travels through this.

What is a medium.

The medium muffles a sound because it does

this.

What is absorb the sound?

No sound is heard in space because

there is no air which means it is this

What is a vacuum?

The three states of matter sound travels through.

What are liquid, solid, and gas?

Sound travels fastest through

this state of matter.

What is a solid?

Sound travels slowest through

this state of matter.

What is air?(gas)

Sound travels faster through

warm air because it

consists of this.

What is air moisture?

Sound travels fastest through this material.

What is steel?

All sound waves carry this.

What is energy?

To vibrate back and forth in the same direction as the wave is know as

this.

What is a longitudinal

wave?

The unit used to measure the loudness of

sound

What are decibels?

The disturbance traveling

through matter and carrying

energy.

What a wave?

Speed of sound is not affected by these two properties.

What are frequency and

amplitude?
