An oscilloscope can be used to accomplish...

🔍 Key Concepts

• Oscilloscope basic purpose – what quantity does it directly display on the screen? • Difference between direct measurements (what the scope actually detects) and derived quantities (what you calculate using other components, like resistors or LEDs). • How an oscilloscope is used in timing and phase measurements.

💭 Think About

• Ask yourself: What does the vertical axis of an oscilloscope actually show, and what does the horizontal axis show? • Which of these options describes something the oscilloscope is only indirectly involved in, where the key phenomenon is not electrical voltage or time? • For each choice, can you describe a realistic lab setup where you would actually do that measurement with a scope?

✅ Before You Answer

• Identify which option does not primarily rely on the oscilloscope’s ability to display voltage versus time. • Check which quantities (electron flow, phase, light velocity, voltage) are normally measured directly with an oscilloscope versus those that require specialized optical or other equipment. • Make sure at least three of the choices can be tied clearly to observing electrical waveforms on the oscilloscope’s screen.

An oscilloscope can be used to accomplish all of the following except:

Measure electron flow with the aid of a resistor.

Measure phase difference between two signals.

Measure velocity of light with the aid of a light emitting diode .

Measure electrical voltage.
