can someone please explain the difference. Graphically and mathematically it is easy to see they are inverses. But I see certain scales like the Richter scale that seem to increase exponentially, but are labeled as logarithmic scales. for example, on the richter scale with each increase in magnitude there is an exponential increase in energy by a factor of 10 i believe. so the difference between a 5 and 6 magnitude earthquake is muuuuch greater than then energy of a 1 and 2 earthquake. seems to me that to graph this you would graph 10^x and have the magnitude on the x axis and the energy on the y axis. but is the ricther scale and other logarithmic scales just the graph of log10x with the magnitude on the y axis and energy on the x axis? seems it is just a matter of how you view it. I know my question is vague, but I'm starting calc II in a week and a half and am trying to prepare as much as possible so any and all information regarding this topic would be very helpful. Thank you.
