🔍 Key Concepts

• Relationship between period and frequency (how often something happens vs. how long one cycle takes) • Conversion between revolutions per second and revolutions per minute (rpm) • How an optical tachometer with one reflective stripe produces one pulse per shaft revolution

💭 Think About

• If one pulse occurs every 0.05 seconds, how many pulses occur in one full second? • Once you know revolutions per second, how do you convert that value to revolutions per minute? • Check whether adding more reflective stripes would change your calculation in this specific problem setup.

✅ Before You Answer

• Confirm that one pulse = one shaft revolution for this problem • Correctly calculate frequency = 1 / period using 0.05 seconds • Multiply revolutions per second by 60 seconds per minute to get rpm before matching a choice
