🔍 Key Concepts

• Standing waves and what causes them on a transmission line • Relationship between load impedance, line characteristic impedance (ZO), and reflections • What it means when all energy is delivered to the load vs when some energy is reflected

💭 Think About

• Think about what must be true at the load for there to be no reflections on the line. Under that condition, would you see standing waves? • If you observe a standing wave pattern, what does that tell you about the match or mismatch between the line impedance (ZO) and the load impedance (ZL)? • Which option describes a situation where not all the power gets into the load and some comes back toward the source?

✅ Before You Answer

• Identify which choice describes a perfect impedance match between the line and the load, and ask: would standing waves exist then? • Decide which answer option explicitly or implicitly indicates that reflected power is present. • Make sure the correct choice is the one that directly connects standing waves to incomplete absorption of power at the load, not to perfect matching.

Question 1 of 27070

Standing waves on a transmission line may be an indication that:

All energy is being delivered to the load.

Source and surge impedances are equal to ZO and ZL.

The line is terminated in impedance equal to ZO.

Some of the energy is not absorbed by the load.
