Anatomy & Properties of Waves

Which best represents the AMPLITUDE?

• distance from points A to D, F to J and A to B

• distance from F to J,B to H and C to F

• distance from E to G, J to B and A to D

• distance from A to D, F to J and B to H

Wave height is another name for ________?

• amplitude

• frequency

• wavelength

• crest

What is measured from crest to crest or trough to trough?

• equilibrium

• wavelength

• amplitude

• frequency

If the frequency of a wave increases, what happens to its wavelength?

• decreases

• increases

• stays the same

• either increase or decrease

If the frequency of the wave decreases, the number of waves per second ______?

• increases

• decreases

• stays the same

• increase then decreases

What part of the wave is point D?

• crest

• trough

• amplitude

• wavelength

A sound wave that has higher pitch means that it has higher frequency. This means that when you hear the sound ________

• more waves hit your ear

• less waves hit your ears

• bigger waves hit your ears

• longer waves hit your ears

All waves carry energy from one place to another, but some waves carry more energy than others. A leaf falling on water produces waves so small they are hard to see. An earthquake under the ocean can produce huge waves that cause great destruction.

What affects the energy of a wave? Select the all that applies.

• The energy in a wave is determined by amplitude, which is the distance from the rest position of a wave to the top or bottom.

• The energy in a wave is determined by frequency, which is the number of waves that pass by each second.

• arge amplitude waves contain more energy.

• The medium (material) moving along with the wave.

A disturbance that transfers energy from place to place through matter or space.

• wave

• equilibrium position

• pulse

• vibration

Frequency is the inverse of period.

Suppose the time from one crest to another is 5 seconds; what is the frequency?

Select the all that apply.

• 0.2

• 1/5

• 0.5

• 1/2
