🔍 Key Concepts

• Inverse distance relationship of field strength with range for groundwave or space wave propagation • How doubling the distance typically affects the field strength when other factors are constant • Relationship between proportional change (x2 distance) and resulting field strength (e.g., x1/2, x1/4, etc.)

💭 Think About

• If field strength at 100 miles is 100 microvolts/meter, what simple ratio can you form when the distance becomes 200 miles? • Does field strength increase, decrease, or stay the same as you move farther from the source, assuming free-space-like conditions? • When distance doubles, does the field strength typically halve, quarter, or change in some other way under the basic exam assumption?

✅ Before You Answer

• Be clear whether the relationship you are using assumes direct proportionality or inverse proportionality to distance • Check which answer choices are smaller than 100 microvolts, since strength should decrease with distance under these assumptions • Confirm that your chosen option matches the expected proportional change when the distance changes from 100 to 200 miles
