🔍 Key Concepts

• Stroboscope flash frequency vs. object rpm and how they interact • The idea of apparent motion (aliasing) when sampling something that is moving periodically • What happens when the flash is slower, equal to, or faster than the true rotation speed

💭 Think About

• Imagine increasing the strobe rate from very slow up to exactly the same as the object’s rpm. How does the apparent motion change as you approach the matching speed? • Now imagine you go slightly past the exact rpm (flash is just a little faster). In which direction would the object seem to drift from one flash to the next? • Compare what you’d see when the flash is slower than the rpm vs. when it is faster. How does that change the apparent direction of rotation?

✅ Before You Answer

• Be clear which is greater: strobe flashes per minute or object revolutions per minute in this question • Mentally test three cases: flash slower than, equal to, and faster than the rpm and picture the apparent motion in each case • Verify which choice matches the situation where flash rate is just above the object’s rpm, not below it
