If an instrument has cramped scale for larger values, then it follows________________?
Correct answer: B. logarithmic law
- A. square law
- B. logarithmic law
- C. uniform law
- D. none of the above
Explanation
A logarithmic scale has decreasing angular spacing for equal increases in the measured quantity, so its graduations become crowded at larger values. A square-law scale is generally crowded near the lower end, not the higher end.
