Waves Intro

Waves transfer ______ from one place to anther.

What direction do particles move in a longitudinal wave?

• Perpendicular to the direction the wave is moving

• Parallel to the direction the wave is moving

• The particles do not move

• The particles move freely in random directions

What is the definition of an 'oscillation'?

• A type of vibration that travels through string

• A regularly repeating motion about a central value

• The time taken for one complete cycle of an oscillation before motion starts to repeat

• The number of complete cycles that occur in one second

What is the definition of 'frequency'?

• A type of vibration that travels through string

• A regularly repeating motion about a central value

• The time taken for one complete cycle of an oscillation before motion starts to repeat

• The number of complete cycles that occur in one second

What is the definition of 'period'?

• A type of vibration that travels through string

• A regularly repeating motion about a central value

• The time taken for one complete cycle of an oscillation before motion starts to repeat

• The number of complete cycles that occur in one second
