Nature of Waves (G9)

Cornell style notes are a great way of recording information because...

• they are easy to do.

• they help organize to make it easy to find and review information

• my teacher makes me do them.

• if I do them well I can go to Cornell University in New York, USA.

A wireless charging device is a great example of the fact that waves…

• can be pulse or continuous.

• are produced by an oscillating object.

• have a wavelength.

• can transfer energy.

Oscillations are…

• a single motion in one direction.

• the material a wave can transfer energy through.

• space that a wave can move through.

• repeating motion of constant period.

Air, water, a tight wire and glass are all examples of…

• media that waves can transfer energy through

• energy that waves can transfer.

• continuous oscillating waves.

• things that cause waves to have a higher amplitude.

In this representation of the distances of a wave, letter A represents the quantity…

• amplitude.

• wavelength.

• equilibrium or center.

• period.

In this representation of the distances of a wave, letter D represents the quantity…

• amplitude.

• wavelength.

• equilibrium or center.

• period.

In this representation of the distances of a wave, letter C represents the quantity…

• amplitude.

• wavelength.

• equilibrium or center.

• period.

The particles in the medium are always moving in the same direction as the energy transmitted by a wave.

• True

• False

The AC electricity provided by the Beijing Power company to all their customers is 50 Hz (hertz). This is a measure of the electricity's …

• wavelength.

• amplitude.

• frequency.

• period.

Water waves crash on a beach every 4 seconds. The water waves have a period of…

• 4 seconds

• 0.25 seconds

• 8 seconds

• 2 seconds
