5/5 Oscilloscope

This is the Cathode Ray Tube we examined in class. We were told that inside the tube, there are 4 plates that help guide the electrons to the end of the tube. The material the end of the tube is made out of turns the fired electrons into a color we can visually see, green. The switch Mason has his finger on changes the orientation of the plates inside causing the electrons, or the green dot, to shift positions.

This is with the Cathode Ray Tube on. We see that the electrons have been fired to the center of the Cathode Ray Tube.

We were asked to predict how the Cathode Ray Tube on the Oscilloscope would change based off a change in voltage from a DC supply, we said the output would be shifted upwards and were correct because the y-axis is in units of voltage and adding voltage would just increase the y-intercept. We then derived formulas for a velocity of an electron given time and length of the magnetic field. We found that using kinematics, we could find that the velocity of the electron is simply the length/time

We used speakers to help determine how frequency sounds at different hertz. We found that the older one gets, the smaller the frequency one can distinguish. 

The above pictures are from our lab with the Oscilloscope.

This was the Mystery Box part of the lab that we came in on Friday to complete. We found that the yellow plug was just for grounding so when whenever we had a combination of two plugs consisting of yellow, the voltage and wave shape was the same as the combination without yellow. 

These were are conclusions as to what the different plugs were.
