What best describes a possible transfer of energy?
A
A mechanical wave transfers energy through matter.B
A longitudinal wave transfers energy perpendicular to wave motion.C
A transverse wave transfers energy parallel to wave motion.D
A sound wave does not need a medium to transfer energy through.3
A sound wave travels through water. What best describes the direction of the water particles?
A
The water particles move perpendicular to the source of the sound wave.B
The water particles move in the same direction as the vibrating source of the sound wave.C
The water particles move in random patterns because the sound is diffracted in many directions.D
The water particles do not move because the sound wave does not have enough energy.4
What is transmitted by all waves?
A
energyB
massC

Following a lecture on transverse and longitudinal waves, four students make Venn diagrams to characterize these waves.Which Venn diagram is correct?
A
A Venn diagram with two intersecting circles. The circle on the left is labeled transverse waves with entries light, can travel through a vacuum, vibrating string, created by a disturbance and medium motion is perpendicular. The circle on the right is labeled longitudinal waves with entries medium motion is parallel, has regions of high and low density, sound and travel faster in a denser medium. The overlapping region has entries has speed and travels through solids.
B
A Venn diagram with two intersecting circles. The circle on the left is labeled transverse waves with entries light, can travel through a vacuum, vibrating string and medium motion is perpendicular. The circle on the right is labeled longitudinal waves with entries medium motion is parallel, has regions of high and low density, sound and travel faster in a denser medium. The overlapping region has entries, created by a disturbance, has speed and travels through solids.
C
A Venn diagram with two intersecting circles. The circle on the left is labeled transverse waves with entries light, all parts of the electromagnetic spectrum, vibrating string, medium motion is perpendicular. The circle on the right is labeled longitudinal waves with entries medium motion is parallel, has regions of high and low density, sound and can travel through a vacuum. The overlapping region has entries, created by a disturbance, has speed and travels through solids.

In an experiment, a ringing bell is placed in a vacuum jar that does not have any air in it. What best describes why the bell is seen vibrating but not heard?
A
Light waves have high frequencies and are able to pass through the vacuum jar, but the frequencies of sound waves are too low to vibrate a vacuum.B
Light waves travel faster than sound waves, so they are able to travel through the vacuum jar, but sound waves do not have enough energy to vibrate glass.C
Light does not need a medium to travel through, but since sound waves must have a medium to vibrate, sound is not created where no air is present.D
Light is a longitudinal wave that is able to pass through the vacuum jar, but sound is a transverse wave that has to move perpendicular to air.8

At the exact time, all students take a step to the right.C
The students skip clockwise, going in a circular motion.D
One at a time, each student lifts his or her hands up and then down.10
