Intro to Waves

What is the best description of a wave?

• Carries matter from one place to another

• A straight line stream of energy

• Carries energy from one place to another

• An up-and-down motion of matter

What is the best description of amplitude?

• The wave is constrained to move along a line instead of moving in other space

• The height of a wave from origin to crest

• The height of a wave from crest to trough

• The number of wave cycles that pass a given point per unit of time

What is indicated by the amplitude of a wave?

• The amount of energy being transferred

• The amount of crests that pass a particular point in time

• The amount of matter being transferred

• The amount of data being transferred

How does a wave's amplitude relate to sound energy?

• The higher the amplitude the softer the sound

• The higher the amplitude there is no change in sound energy

• The higher the amplitude the louder the sound

• Amplitude is the same as pitch

How does a wave's frequency relate to pitch?

• The higher the frequency the higher the pitch

• The higher the frequency the lower the pitch

• The higher the frequency there is no change in pitch

• Pitch is related to amplitude, not frequency

A particular wave's energy is doubled as its amplitude increases. Which of the following most closely represents this model?

• Amplitude 8, Energy 4

• Amplitude 3, Energy 18

• Amplitude 2, Energy 2

• Amplitude 3, Energy 6
