Properties of Waves

What is the definition of amplitude in wave motion?

• The time in seconds for one wave to pass a point

• The maximum displacement of a point on a wave away from its undisturbed position

• The number of waves passing a point each second

• The distance from a point on one wave to the equivalent point on the adjacent wave

What symbol is used to represent wavelength?

• Gamma (γ)

• Alpha (α)

• Beta (β)

• Lambda (λ)

How is the frequency of a wave defined?

• The time it takes for a wave to complete one cycle

• The maximum height of a wave

• The number of waves passing a point each second

• The distance between two consecutive crests or troughs in a wave

What is the unit of frequency?

• Meters (m)

• Hertz (Hz)

• Watts (W)

• Seconds (s)

How do you calculate the period of a wave?

• Multiply the frequency by the wavelength

• Divide 1 by the frequency in Hertz

• Add the amplitude to the wavelength

• Subtract the wavelength from the amplitude

If a wave has a frequency of 100 Hertz, what is its period?

• 1 second

• 10 seconds

• 100 seconds

• 0.01 seconds

What type of wave was primarily discussed for labeling amplitude?

• Longitudinal wave

• Transverse wave

• Surface wave

• Sound wave

How can wavelength be measured in a longitudinal wave?

• From amplitude to amplitude

• From crest to crest

• From trough to trough

• From one compression to the next compression

What does a frequency of 5 Hertz mean?

• 5 waves pass a point in 1 second

• 5 waves pass a point in 5 seconds

• 5 waves pass a point in 1 minute

• 5 waves pass a point in 2 seconds
