The spacing interval of markers is between which values?

• A. 10 to 100
• B. 0 to 10
• C. 100 to 200
• D. 5 to 15

Answer: (A)

Marker spacing is about choosing a practical distance so you can clearly resolve each marker’s signal while covering enough length to capture the event. The range from 10 to 100 units gives a good balance: far enough apart so signals don’t blur into each other, but close enough that rapid changes aren’t missed. If markers are spaced too tightly, signals can overlap and timing becomes unreliable. If they’re spaced too far apart, you miss important dynamics between markers and lose resolution. Spacings near zero to ten units are usually too tight for reliable discrimination, while spacing beyond about a hundred units becomes too sparse to track the event accurately. A middle-ground interval of 10 to 100 units aligns well with typical detector capabilities and measurement needs.
