7 questions

Question 1

A sound wave is a pressure wave; regions of high (compressions) and low pressure (rarefactions) are established as the result of the vibrations of the sound source. These compressions and rarefactions result because sound

vibrates longitudinally; the longitudinal movement of air produces pressure fluctuations.

is able to reflect off fixed ends and interfere with incident waves

is like all waves; it is able to bend into the regions of space behind obstacles.

waves have a speed that is dependent only upon the properties of the medium.

is more dense than air and thus has more inertia, causing the bunching up of sound.

Question 2

Describe the picture using:

Particles
Disturbance
Parallel
Energy

Question 3

A sound wave is different than a light wave in that a sound wave is

produced by an oscillating object and a light wave is not.

capable of existing with a variety of frequencies and a light wave has a single frequency.

not capable of diffracting and a light wave is.

not capable of traveling through a vacuum.

Question 4

Which of these has a 'Higher' frequency?

Question 5

Which of these has a 'Higher' period?
