Properties of Waves

What is wavelength?

• total amount of time it takes a wave to move through one cycle

• distance between a point on a wave and the EXACT same point on the next wave

• number of crests and troughs a wave produces in one minute

• length of a series of waves traveling from a source

Which best describes a wave?

• disturbance that carries energy

• kind of motion that pushes objects

• form of energy that makes heat

• type of matter

What is amplitude?

• distance a wave travels in a given amount of time

• number of disturbances produced by a wave

• total distance a wave moves from its resting position

• distance between the crest and trough on a wave

What is the relationship between frequency and amount of energy in a wave?

• Waves with lower frequencies have more energy.

• Changes in frequency never change the energy of the wave.

• Waves with higher frequencies have more energy.

• Changes in frequency only change the energy of the wave if it is a longitudinal wave.
