Two of the statements are true. One is false. Choose the ONE that is FALSE.

• All waves are created by vibrating objects

• When a mechanical wave moves through a medium, the particles of the medium vibrate but do not change their position

• An ocean wave transports water from a distant off-shore location to a location near the shore

Answer explanation

Check slide 4. Do waves transport matter or energy?

Two of the statements are true. One is false. Choose the ONE that is FALSE.

• When a mechanical wave moves through a medium, particles vibrate back and forth but don't move from one location to another

• A wave transports energy through a medium without transporting material

• A sound wave causes particles of air to travel from the source of sound (i.e. the speaker) to the listener's ear

Answer explanation

Check slide 4. Do waves transport matter or energy?

Two of the statements are true. One is false. Choose the ONE that is FALSE.

• When a wave moves through a medium, particles of the medium move along a curved path from one end to the other

• A wave transports energy from the source to a distant location

• A wave moves through a medium because Particle A pushes on Particle B, which pushes on Particle C, which pushes on Particle D, which pushes on ...

Match the type of wave to its definition

• Transverse wave

• Requires a material in order to move between locations

• Electromagnetic wave

• This type of wave can move through a vacuum (a space with no air)

• Longitudinal wave

• Particle motion and wave motion are perpendicular to each other

• Mechanical wave

• Particle motion and wave motion are parallel to each other

Answer explanation

Transverse- up and down. Longitudinal- back and forth. Electromagnetic- light. Mechanical- everything else on Earth.

Label which locations represent a crest, a trough, a compression, or a rarefaction. Some categories may be used more than once. Some categories may not be used at all.

Groups:

(a) compression

,

(b) rarefaction

,

(c) crest

,

(d) trough

• B

• D

• none

• C

• A

• also none

Answer explanation

remember- longitudinal is stretch and squish (not up and down)

Identify the direction of vibration of the particles in the rope at each point of the wave. Some categories may have more than one answer choice. Some categories may be a trick.

Groups:

(a) up and down

,

(b) side to side

,

(c) in a circle

• C

• D

• B

• A

• not possible

• none

Answer explanation

transverse- particle movement is perpendicular to wave movement at EVERY point
