Which among the following is a logarithmic scale?
-
Linear encoder
-
Richter Scale
-
Pneumatic Scale
-
Hyperbolic encoder
B
Correct answer
Explanation
The Richter Scale measures earthquake magnitude using a base-10 logarithmic scale, where each whole number increase represents a tenfold increase in amplitude. This logarithmic design allows the scale to cover the enormous range of earthquake energies, from barely detectable to catastrophic.
