Complete the homework by answering each of the following questions. You may use your notes from class. Once the assignment is complete, print a report showing your completion record. This report will be submitted in class for a grade.

• 1.

### Waves are created by a vibration.

• A.

True

• B.

False

A. True
Explanation
Waves are indeed created by vibrations. When an object vibrates, it creates a disturbance in the surrounding medium, such as air or water. This disturbance then travels through the medium, causing particles to oscillate and transfer energy. These oscillations create a wave, which can be observed in various forms, such as sound waves or water waves. Therefore, the statement "Waves are created by a vibration" is true.

• 2.

### As a wave moves through a medium, the individual particles of the medium move from the source of the wave to another location some distance away.

• A.

True

• B.

False

B. False
Explanation
False. As a wave moves through a medium, the individual particles of the medium oscillate back and forth about their equilibrium positions, but they do not move from the source of the wave to another location some distance away. The energy of the wave is transferred through the medium, but the particles themselves do not undergo a net displacement.

• 3.

### Waves are a means of transporting energy from one location to another without actually displacing matter from one location to another.

• A.

True

• B.

False

A. True
Explanation
Waves are indeed a means of transporting energy without displacing matter. This is because waves are disturbances that travel through a medium, causing the particles of the medium to vibrate or oscillate, but without actually moving the particles from one location to another. As the wave propagates, energy is transferred from one particle to the next, resulting in the transportation of energy through the medium. Therefore, the statement "Waves are a means of transporting energy from one location to another without actually displacing matter from one location to another" is true.

Rate this question:

• 4.

### An ocean wave will transport ocean water from near the middle of the ocean to a location near the shore.

• A.

True

• B.

False

B. False
Explanation
Ocean waves do not transport ocean water from near the middle of the ocean to a location near the shore. Instead, ocean waves transport energy through the water, causing the water particles to move in a circular motion. This circular motion of water particles does not result in a net transport of water from the middle of the ocean to the shore. Therefore, the statement is false.

Rate this question:

• 5.

### As mechanical waves move through a medium, particles of the medium undergo a periodic and repeated vibration about a fixed position.

• A.

True

• B.

False

A. True
Explanation
Mechanical waves are characterized by the transfer of energy through a medium by the vibration of particles. As the wave propagates, the particles of the medium oscillate back and forth about their equilibrium positions. This periodic and repeated vibration is a fundamental characteristic of mechanical waves, such as sound waves or waves on a string. Therefore, the statement "As mechanical waves move through a medium, particles of the medium undergo a periodic and repeated vibration about a fixed position" is true.

Rate this question:

• 6.

• 7.

### Mechanical waves propagate or move through a medium because ________.

• A.

The particles of the medium are able to move along the curved wavelike pathway

• B.

One particle pushes or pulls on the adjacent particle which pushes or pulls on the next particle

• C.

The initial vibration of the medium causes the medium to assume the wavelike shape and this shape subsequently moves from one location to another.

B. One particle pushes or pulls on the adjacent particle which pushes or pulls on the next particle
Explanation
Mechanical waves propagate or move through a medium because one particle pushes or pulls on the adjacent particle which pushes or pulls on the next particle. This is how the energy of the wave is transferred from one particle to another, causing the wave to propagate through the medium. Each particle in the medium acts as a source of disturbance, which then causes a chain reaction of pushing and pulling on the neighboring particles, resulting in the movement of the wave.

Rate this question:

• 8.

### Which of the following categories of waves require a medium in order to transport energy from one location to another?

• A.

Mechanical

• B.

Electromagnetic

A. Mechanical
Explanation
Mechanical waves require a medium in order to transport energy from one location to another. This is because mechanical waves are created by the vibration or disturbance of particles in a medium, such as air, water, or solids. As the particles vibrate, they transfer energy to neighboring particles, causing the wave to propagate through the medium. In contrast, electromagnetic waves do not require a medium and can travel through empty space, as they are composed of oscillating electric and magnetic fields.

Rate this question:

• 9.

### The arrows on the diagrams below represent the direction of particle motion. Diagram A shows a ____ pulse and diagram B shows a ____ pulse.

• A.

Longitudinal, transverse

• B.

Transverse, longitudinal

B. Transverse, longitudinal
Explanation
In transverse waves, the particles of the medium vibrate perpendicular to the direction of wave propagation, forming crests and troughs. This is represented by the diagram A, where the arrows are perpendicular to the wave direction. In longitudinal waves, the particles of the medium vibrate parallel to the direction of wave propagation, forming compressions and rarefactions. This is represented by diagram B, where the arrows are parallel to the wave direction.

Rate this question:

• 10.

### Compare the direction in which particles of the medium vibrate for a longitudinal wave compared to a transverse wave. Reference the diagram in question #9 in your discussion.
