In general we can say that for longitudinal waves, the direction of motion of the particles that make up the wave move

• parallel to the direction of motion of the wave

• perpendicular to the direction of motion of the wave

• not at all as the disturbance passes through the material

As the energy of a wave travels through a medium, the ______________is momentarily displaced.

 

• matter

• energy

• frequency

• period

The following is a mechanical pulse that is moving from right to left. For the situation shown, we can say that as the wave moves to the left, the dot will move

• to the right

• to the left

• downwards

• upwards

For the diagram, the wavelength is:

• 2 m

• 4 m

• 6 m

• 8 m

For the diagram, the amplitude is:

• 1 m

• 2 m

• 4 m

• 8 m

For the diagram, if the frequency of this wave is 5 Hz, then how far will a particle in the string travel each second?

• 4 m

• 16 m

• 40 m

• 80 m

In free end reflection and in the “ideal” case (no frictional loss), the reflected pulse is

• on the same side, of the same wavelength

• on the opposite side, of the same wavelength

• on the same side, of a different wavelength

• on the opposite side, of a different wavelength
