Decade (log scale)

A decade in a logarithmic scale refers to a multiplicative factor of ten. In mathematics and science, logarithmic scales are often used to represent data that spans multiple orders of magnitude. For example, when dealing with phenomena like earthquakes (Richter scale), sound intensity (decibels), or pH levels, a logarithmic scale simplifies the representation of very large or very small numbers. In a logarithmic scale, each unit increment represents a tenfold increase or decrease.
