1. Waves and Oscillation
waves transport _________ along a medium without transporting ________

2. Types of Waves
_______________ Waves
_________________Waves

3. Anatomy of a wave
_______________: the highest point a wave reaches. The lowest point is called its trough.
_______________: the vertical distance in meters from a wave’s crest to its trough.
_______________: the horizontal distance between two successive crests, often measured in meters.

4. Amplitude: _____________________ _______________________________.
the displacement of the medium from zero or the height of a wave crest or trough from a zero point.
In the BOSS activity it’s how far to the _________________
_________________.

5. Period:____________________________________________
__________________________________________________.

6. Oscillation: the repeating motion of a wave or a material—_____________________________________________.
Earthquakes cause seismic waves that produce oscillations in materials with many different frequencies.
Every object has a ___________ _________ of vibration that scientists call its natural frequency. The natural frequency of a building depends on its physical characteristics, including the design and the building materials.

7. Frequency: _____________________ _______________________________.
number of oscillations in an earthquake wave that occur each second.
unit for frequency is the __________
1 Hz = __________________.
In earthquake engineering, frequency is the rate at which the top of a building sways.

8. Resonance: _______________________________________________
In the case of an earthquake: When the frequency of oscillations due to earthquake waves is close to that of the natural frequency of the building the motion is amplified.

9. Buildings always oscillate in an earthquake.
1985 Mexico City
ground shaking ____________________________________________________________.
severe damage to medium-height buildings that had the same frequency as the ground shaking and resonated with it.
Higher and lower buildings were hardly damaged.

10. Seismic sea wave: _______________ _______________________________.
Tsunami: a potential destructive ocean wave created by an earthquake or other large-scale disturbance of the ocean floor.
