Properties of a wave

Multiple Choice

During a baseball game, fans in the stands create a “wave” by standing up from their chairs when the wave arrives at their location. Which sentence classifies this type of wave and its particle motion?

• It is a transverse wave in which the particles of the wave move in a direction parallel to the wave motion.

• It is a longitudinal wave in which the particles of the wave move in a direction perpendicular to the wave motion.

• It is a transverse wave in which the particles of the wave move in a direction perpendicular to the wave motion.

• It is a longitudinal wave in which the particles of the wave move in a direction parallel to the wave motion.

Multiple Choice

Which of the following best describes a longitudinal wave?

• A disturbance that moves the medium along its line of travel.

• A wave that is caused by regularly repeating disturbance of the medium.

• A disturbance that moves the medium outward in all directions from a center.

• A disturbance that moves the medium perpendicular to its line of travel.

Multiple Choice

The waves that are produced by a person’s voice are similar to the waves produced by an earthquake because both are...

• caused by physical vibrations.

• types of electromagnetic waves.

• moved by the force of gravity.

• of the same frequency.

Multiple Choice

Jon is holding a rope from one end. He is swinging it up and down steadily.

What kind of a wave is Jon making?

• Mechanical, transverse.

• Mechanical, longitudinal.

• Electromagnetic, longitudinal.

• Electromagnetic, transverse.

Multiple Choice

Which of the following describes a characteristic of ALL waves?

• All waves move energy from one place to another.

• All waves travel through a vacuum.

• All waves cause particles to move back and forth.

• All waves carry matter from one place to another.

Multiple Choice

Which of the following best describes a transverse wave?

• A wave that is caused by regularly repeating disturbance of the medium.

• A disturbance that moves the medium outward in all directions from a center.

• A disturbance that moves the medium perpendicular to its line of travel.

• A disturbance that moves the medium along its line of travel.

Multiple Choice

The image shows a mechanical wave.

Which number indicates the wavelength of this wave?

• 1

• 2

• 3

• 4

Multiple Choice

A __________ is the highest point of a transverse wave. The lowest point of such a wave is called a _________.

• amplitude; longitudinal

• amplitude; trough

• crest; trough

• crest; longitudinal

Multiple Choice

Which wave has the highest energy?

• A high-amplitude, high-wavelength wave.

• A high-amplitude, low-wavelength wave.

• A low-amplitude, low-wavelength wave.

Multiple Choice

Seismic waves carry energy from earthquakes through the earth's crust. Seismic waves are...

• both transverse and longitudinal waves.

• longitudinal waves only.

• transverse waves only.

• neither transverse nor longitudinal waves.

Multiple Choice

When an earthquake occurs, the speed of the seismic waves changes as they...

• are pulled by the force of gravity.

• lose energy to surrounding rocks.

• move through different materials.

• reflect off boundaries.

Multiple Choice

After an earthquake, the last waves to arrive at a distant location are _________.

• P-waves

• surface waves

• S waves

• sound waves

Multiple Choice

Which statement correctly describes the main difference between body waves and surface waves?

• Surface waves are less damaging to man-made structures than body waves.

• Surface waves travel across the earth’s surface, and body waves travel through the earth’s interior.

• Surface waves only travel across oceans, and body waves travel across the earth’s crust.

• Surface waves are only longitudinal waves, and body waves are only transverse waves.

Multiple Choice

P-waves move fastest through the inner core of the earth.

What does this tell us?

• The inner core is the densest part of the earth.

• P-waves cannot move through the outer core.

• The mantle is denser than the inner and the outer core.

• P-waves are the fastest seismic waves.

Multiple Choice

P-waves slow down when entering less dense medium. P-waves slow down when entering the outer core.

What does this tell us about interior of the earth?

• The outer core is denser than the mantle.

• The outer core is denser than the inner core.

• The outer core is less dense than the inner core.

• The outer core is less dense than the mantle.

Multiple Choice

How do scientists use data from earthquake S waves to study the earth?

• S waves pass through liquids but not solids, so scientist can determine the location of the core.

• S waves pass straight up from where an earthquake occurs, so scientists can identify the location of the core.

• S waves cannot pass through solids or liquids, so scientists can determine the location of the mantle.

• S waves pass through only solid rock, not liquid, so scientists can determine that the outer core is liquid.

Multiple Choice

lose energy to surrounding rocks.

• S waves move faster than P-waves.

• P-waves can only travel through solids; S waves can travel through all mediums.

• S waves are transverse waves, and P-waves are longitudinal waves.

• P-waves are transverse waves, and S waves are seismic waves.
