Oscilloscopes

During this lab section, we focused on learning a new equipment, the oscilloscope. We focused on how to set it up, get it working, and even how to use it for certain crucial parts within the lab

In the beginning portions, Prof Mason shows us how the oscilloscope works. The fact the we turned it on and its moving (in AC set up) means that it is picking up the wall current

Sample problems using past knowedge

In this sample problem, we were able to once again relate what we are learning now to what we have learned in Phys 4A, as we derive a few equations, using our constant acceleration model from Phys 4A/Phys 2AG

In the clips below, we are shown how the function generator operates. How at low frequencies, we can hear the choppy sounds that it makes due to the sinusoidal waves being so long, and as the frequency increases, the sinusoidal waves length decrease, eventually creating one flat sound, know as resonance

 
In the picture below, we were asked to play around with the function generator, writing down the sounds it makes as we changed the setting to both square and triangle setting, along with when we increase the frequency and the amplitude of the generator.

The next pictures is an experiment we did by working alongside a battery. We are asked to find the battery's voltage, as we played more with the voltage, learning how to read volt/div

Our answers to the question provided

In these photos, we were asked to find the actual frequency being produced in the oscilloscope based on the period of the graph. We then took what we found, and calculated the frequency to find the percent difference, which turned out to be pretty small

The bottom two pictures display me playing around with the connection of the oscilloscope. When I am touching the positive and negative ends of the oscilloscope, the oscilloscope responds to me, meaning that my body naturally generates some voltages that the oscilloscope is picking up (note that the settings is in AC when this part of the experiment is being conducted)

By mixing two systems together in the oscilloscope, we are able to produce interesting shapes and figures, which can be adjusted depending on the setting of the function generator.

The next few pictures is our attempt at what Prof Mason has shown and provided for us

In this final part of the lab, we are given a mystery box, that produces different readings from the oscilloscope, some might be in DC settings, others might be in AC. Our goal was to find out what each color coded plug in produced, and whether it was in DC or AC
It is to note that everyone's mystery box differed, and that our answers are correct, despite all being in DC.
