A log-log scale is a set of axes where each axis is logarithmic in scale.
pH is a logarithmic scale; because of the way calculus and maths works, graphing such a scale against a log results in a straight line.
Whenever the data covers a very large range of values a log scale if very useful. Earthquakes and hearing are common examples.
For a quotient x/y , then its log is logx - log y . NOT log(x/y)

k=log4 91.8 4^k=91.8 -- b/c of log rules-- log 4^k=log 91.8 -- b/c of log rules-- k*log 4=log91.8 --> divide by log 4 k=log 91.8/log 4 k= 3.260
It is called the magnitude scale. It is a log scale.
Many scales such as sound and PH are log scales. The scale used to measure earthquakes is also a log scale. Whenever the data has a very wide range, a log scale might help.
One axis (usually the vertical axis) is on a log scale, the other is a linear scale.
pH is a logarithmic scale; because of the way calculus and maths works, graphing such a scale against a log results in a straight line.
The Doyle Log Scale, developed around 1825, is based on a mathematical formula and is widely used throughout the southern United States. This rule allows for a saw kerf of 5/16 inch (most circular mills). Because of this, the Doyle Rule is somewhat inconsistent; it underestimates small logs and overestimates large logs. To use a Doyle Log Scale measure the diameter of the log (not including the bark) and the length. Then using the Doyle scale you can calculate the board foot content of a log.
The pH scale is called a log scale because each unit increases or decreases logarithmically. What this means is that if you were to go from a pH of 7 to a pH of 8 you have increased your concentration of -OH ions ten fold or from a pH of 7 to a pH of 9 would be a 100 fold increase of -OH concentration. Incidentally, pH refers to a mathematical equation where p is the inverse log of H+ (acid/protons) concentration in solition. Thus we are measuring the inverse log concentration of H+ ions or simply put: pH.The equation looks like the following: pH = -log[H+]
Verners are a measuring device used to measure size that is based on the log scale.
The Ph scale doesn't have units it's a model to show where solutions rank based on the -Log of the concentration of H+ ions
It is a coordinate system or graph paper in which one axis (usually the y-axis) is to a logarithmic scale and the other (x-axis) is "normal".
The decibel log scale measures sound intensity by comparing the sound pressure level to a reference level. It uses a logarithmic scale to represent the wide range of sound intensities that humans can hear. Each increase of 10 decibels represents a tenfold increase in sound intensity.
Semilog (applied to a graph) means that one scale is logarithmic, the other not. The prefix "semi-" means "half" or "partially". The scale that is not logarithmic is, of course, linear.
log is short for logarithm log(base a)x=y is the same as saying a^y=x Normal log is base 10. So if you see log with no subscript after it, it is log base 10. So when you press the log button on your calculator and put a number after it you are asking 10 to what power =100? And 10 to the second power = 100 so you will get an answer of 2. A log (base 5)625 you would be asking, 5 to what power is equal to 625? The answer is 4 because 5^4=625 Logarithms are used to simplfy complex calculations. The Richter scale for measuring earth quakes is expressed in the form of a logarithm. A increase of 1 on the scale means an increase of 10 times.
