Chapter 10: Waves

Diffraction

Diffraction

________: occurs when an object causes a wave to change direction and bend around it.

Seismic Waves

When objects on Earths surface absorb some of the energy transferred by ________, they move and shake.

Wave

________: a repeating disturbance or movement that transfers energy through matter or space.

Resonance

________: The process by which an object is made to vibrate by absorbing energy at its natural frequencies.

Rarefactions

________: less-dense regions of a compressional wave.

Refraction

________: the bending of a wave caused by a change in its speed as it moves from one medium to another.

Amplitude

________: related to the energy transferred by a wave.

Interference

________: When two or more waves overlap and combine to form a new wave.

Ocean Waves

________ are formed most often by wind blowing across the ocean surface.

Period

________: the amount of time it takes one wavelength to pass a point.

Frequency

________: the number of wavelengths that pass a fixed point each second.

Light Waves

________ travel more slowly in water than in air.

Sound Waves

________ usually travel faster in liquids and solids than they do in gases.

Medium

________: can be a solid, a liquid, a gas, or a combination of these.

Diffraction

________ and refraction both cause waves to bend.

Constructive Interference

________ also occurs when the compressions of different compressional waves overlap.

Sound

________ waves also can travel through other mediums, such as water and wood.

Amplitude

________ is measured differently for compressional and transverse waves.

Sound Waves

________ travel through the air to reach your ears.
