🔍 Key Concepts

• Relationship between oscillator frequency (kHz) and distance between range markers (NM) on the radar or LORAN-like display • How period of a signal (time for one cycle)** is related to its frequency** • Typical scale factors used in exam questions: when frequency doubles or halves, what happens to marker spacing?

💭 Think About

• First, recall or derive the basic formula that links frequency and time period; then think about how that time period translates into a distance on the screen using the speed of propagation. • Ask yourself: if the oscillator frequency is increased, do the range markers get closer together or farther apart? • Try to remember a ‘reference’ pair (e.g., a common exam value of kHz and the corresponding NM spacing) and scale up or down from that using proportional reasoning.

✅ Before You Answer

• Make sure you are using the correct proportional relationship: range-marker spacing is inversely proportional to oscillator frequency. • Check that you are thinking in nautical miles, not yards or statute miles. • Before choosing, eliminate any options that would imply that higher frequency produces larger spacing, since that would contradict the inverse relationship.
