Exploring waves virtual lab

_________ is the distance from the rest position to the crest or to the trough

2. During any up-and-down cycle of the particle, does it move with a constant speed or with a changing speed?

3. For transverse waves, compare:

the direction that the particles move

to

the direction that the wave moves.

Is parallel or perpendicular?

4. Set the animation to a low frequency (about 0.1 Hz) and observe the wave speed.

set the animation to a high frequency (about 1.2 Hz) and observe the wave speed.

Does changing the frequency value change the wave speed in this animation?

5. Now change the amplitude and observe the wave speed.

Does a change in amplitude effect the wave speed?

During any compression and rarefaction of the particle, does it move with a constant speed or with a changing speed?

3. For longitudinal waves, compare:

the direction that the particles move

to

the direction that the wave moves.

Is parallel or perpendicular?

4. Set the animation to a low frequency (about 0.1 Hz) and observe the wave speed.

set the animation to a high frequency (about 1.2 Hz) and observe the wave speed.

Does changing the frequency value change the wave speed in this animation?

5. Now change the amplitude and observe the wave speed.

Does a change in amplitude effect the wave speed?

1. For a transverse wave, the particles of the medium move ______ to the direction that the wave moves.

2. For a longitudinal wave, the particles of the medium move ______ to the direction that the wave moves.

3. Sound waves are _____.

4. Increasing the amplitude of sound waves changes the sound’s speed.
