PhysicsLAB: Waveform and Vibration Graphs #2

This worksheet is divided into three parts. The top set of questions revolve around a wave with point P, the second set of questions involve a different wave with point Q, and the third section involves a more extensive vibration graph.

Refer to the following information for the next six questions.

Vibration graph of point P

Waveform graph at t = 10 seconds (P is at 10 cm)

waveform graph of P

What is the amplitude of this first wave involving point P?

What is the wavelength of this wave?

What is the period of this wave?

What is the frequency of this wave?

What is the wave's speed?

On which side of the waveform graph, or snapstot, was the source causing this disturbance?

Refer to the following information for the next seven questions.

Vibration graph of point Q

vibration graph of Q

Waveform graph at t = 10 seconds (Q is at 20 cm)

waveform graph of Q

What is the amplitude of this second wave involving point Q?

What is the wavelength of this second wave?

What is the period of this second wave?

What is the frequency of this second wave?

What is the speed of this second wave?

On which side of the original waveform graph, or snapshot, was the source causing this disturbance?

If the energy of a wave is proportional to the square of its amplitude, how does the energy in the second wave (point Q) compare to that of the first wave (point P)?

Refer to the following information for the next two questions.

What is the frequency of the vibrations illustrated in the diagram above?

What is the amplitude of the vibrations illustrated in the diagram above?
