With an app downloaded on a phone which was then connected to an oscilloscope, we used it to visually see the sound waves emitted by the phone. At certain hertz, we were able to see the different types of waves that is emitted. As the hertz level was raised, the higher the peaks of the waves.
We now turned on a song to see what the oscilloscope would display and it displayed sharp and fast waves.
We then connected to the circuit the speaker to see if the speaker would emit the song.
Although the oscilloscope was displaying that the circuit was connected well, the speaker was not working properly. It may have been a circuit problem within the speaker or our wires were not connected properly.
Next, Professor Mason provided us with some bread boards and a red light bulb. He told us to build a circuit with a capacitor to light up the red light bulb.
The little holes are connected to each other in a column and with some extra circuit wires and an external battery, we were able to light up the red light bulb.
This is an overhead view of the circuit. We were also given a resistor to add the circuit.
The capacitor acts like an on and off button for this circuit.
This is the capacitor.
This is what we had to work with. The external energy source and speakers were connected but not turned on. The box contained the extra wiring we may have needed.
We tested the condition of our bread board by connecting it to the oscilloscope.
Something was being emitted..
This was the end result of our bread board.
At last, we connected it to the external energy source and speakers and as we pressed the capacitor button, the speakers were able to emit music with much difficulty.
