Wave Properties and Measurements

What do mechanical waves need to travel through?

• A vacuum

• A medium

• A force field

• A magnetic field

Which of the following can be a medium for mechanical waves?

• Vacuum

• Solid, liquid, or gas

• Light

• Sound

What is a cycle in terms of wave motion?

• A wave that never returns

• One complete wave motion

• Half of a wave motion

• A wave that stops midway

How is the period of a wave measured?

• In meters

• In seconds

• In liters

• In kilograms

What does frequency tell us?

• How many cycles happen in one second

• The distance between two waves

• The speed of light

• The color of a wave

In what unit is frequency measured?

• Meters (m)

• Seconds (s)

• Hertz (Hz)

• Kilograms (kg)

What happens when there are more cycles per second?

• Lower frequency

• Higher frequency

• No change in frequency

• Frequency becomes zero

What is the relationship between frequency and period?

• They are the same

• Frequency is double the period

• Frequency and period are opposites

• Frequency is half the period

What is wavelength?

• The height of a wave

• The distance between a point on one wave and the exact same point on the next wave

• The speed of a wave

• The color of a wave

In transverse waves, what is the wavelength measured from?

• Crest-to-crest or trough-to-trough

• Start-to-end

• Top-to-bottom

• Side-to-side
