Two sound waves are emitted from identical sources at the same time. They each travel a distance of 10 m, but one wave reaches the destination faster than the other. What can you conclude about the two waves?

A wave emitted from a source has a frequency of 10 Hz and wavelength 2.5 m. How much time will it take to reach a person located 5 m from the source?

Two students are holding opposite ends of a spring in a classroom. One student stands on the left end of the classroom and the other stands at the right end. They shake the spring so that a longitudinal wave travels along the spring. In which directions will the longitudinal wave oscillate?

1

Examine the two waves shown. Which wave has a greater amplitude?

1

Observe the following diagram of the electromagnetic spectrum. What term should be written in the blank space shown?

1

Match the following

Draggable item		Corresponding Item
Refraction		occurs when a wave strikes a boundary between two media and bounces back into the medium from which it was originally traveling.
Resonance		occurs when a wave changes speed. This causes the wave to bend, and it typically occurs when wave moves from one medium to another.
Polarization		in terms of transverse waves, it describes the orientation of the oscillations relative to the direction in which the wave propagates.
Interference		occurs when two or more waves interact with each other. The new wave is a combination of the original two, with the amplitude equal to the sum of the two waves individual amplitudes.
Diffraction		the spreading out of waves when they encounter a barrier or a narrow opening
Reflection		the tendency of an object to vibrate with a greater amplitude at a particular frequency, known as the resonant frequency.

Earthquakes ___________________  that travels through solid ground in the form of seismic waves. Potential energy builds up as a result of ___________  on rocks along cracks in Earth’s crust called ___________ . The stress occurs because pieces of Earth’s lithosphere called tectonic plates are in constant motion. This motion causes rock on either side of a fault to ___________ , or show strain. Eventually, the stress becomes so great that ________________ , moving suddenly along the fault. Earthquakes generate several different types of seismic waves. Some seismic waves travel through Earth’s interior. Geologists refer to these as _________  waves because they move through bodies of rock. Other seismic waves, called ____________  waves, travel along the surface of the ground.

Other Answer Choices:

faults

release energy

rock breaks

deform

surface

stress

body

____________  waves give scientists information about the structure of Earth's interior layers. Seismic P waves are called ______________  waves because they are the first seismic waves felt or recorded following an earthquake. Seismic P waves are also referred to as __________________  waves while seismic S waves are referred to as __________  waves. Surface waves are the ____________  type of seismic wave, whereas the ____________  seismic waves are P waves. To measure earthquake waves, scientists use a ________________ . _______________  include both P waves and S waves.

Other Answer Choices:

compressional

slowest

"primary"

fastest

shear

seismometer

4

A seismic ___________  zone is an area of the Earth's surface where seismographs __________________  P waves and/or S waves from an earthquake.
