Description:

Put a green laser on a stand and shoot it through the length of the tube. You will see maxima and minima along the lasers path due to the circular polarizing effect of karo syrup. If you change the angle at which you view around the lasers path you will note the maxima and minima change as well.

Still need to find a slide projector…

111-14D

Description:

The track was designed specifically for the carts in Physics 111 so that they would easily hit each other  without much need for aiming.

Description:

On the ringing demo box turn the 5K and 10K dials fully CCW with the switch flipped to scope.

Set the audio generator to about ~900 Hz, O-db, and rotate the fine knob to the 2 o’clock position, with a square wave.

Set the oscilloscope to channel 1 only, and press “autoset”. Then press the “trigger menu” button and set the coupling to LF Reject. The rest of the settings should say slope: rising, mode: auto, and type: edge. Finally adjust the “trigger-level” for a clean waveform.

At this point the image on the scope should just need to be moved to resemble the picture to the below.

Now adjust the 5K and 10K dials and note the change [increased damping]

Then vary the frequency on the audio generator to show the absence of any change in the frequency of the ringing waveform displayed.

Description:

Drop a cow magnet down a copper pipe and then drop a steel “cow magnet look-a-like” down the copper pipe and compare the time it takes to fall.
