Sound

How does sound travel?

• Vibration of particles moving in a snakelike pattern

• Vibration of particles moving in a wavelike pattern

• Stillness of particles moving in no pattern

• Vibration of particles moving in a straight pattern

The two separate areas (from speaker to ear) shown in the soundwave are?

• condensation & radiometrics

• rarefaction & condensation

• radiometrics and compression

• rarefaction & compression

Amplitude is the description of:

• distance the air particles travel

• distance the sound particles travel

• time the air particles travel

• time the sound particles travel

Vocal chords can alter the number of vibrations every:

• second. The less vibrations the lower the pitch

• second. The more vibrations the higher the pitch

• second. The less vibrations the higher the pitch

• second. The more vibrations the lower the pitch

When sound waves travel the difference in notes/pitches are?

• The lower the note/pitch the further apart sound particles travel

• The higher the note/pitch the further apart sound waves travel

• The lower the note/pitch the closer together sound waves travel

• The higher the note/pitch the closer together sound waves travel

Frequency is:

• Number of sound particles that pass a point each second

• Number of sound waves that pass a point each second

• Number of sound waves that pass a point each millisecond

• Number of sound particles that pass a point each millisecond

Hertz is the measurement of:

• algorithm

• Bandwidth

• Frequency

• Superposition

when you scream in space the distance a person can hear you is?

• all are incorrect

• 10 cm

• 10m

• 1 cm
