Question

Define Richter scale.


pls tell​

Answer 1

Answer:

The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included for the variation in the distance between the various seismographs and the epicenter of the earthquakes

$\sf\huge\bold{Answer:}$

• Definition:

The Richter scale  is a logarithmic scale that calculates an earthquake's magnitude (size) from the amplitude of the earthquake's larger seismic wave recorded by a seismograph.[the smaller magnitude is considered nearly 0]

• Measure:

The scale has no upper limit but usually ranges from 1 to 9. Because it is logarithmic, an earthquake rated as 5 is ten times as powerful as one rated as 4.

• Invention:

Richter Scale was developed in 1935 and named after by Charles F. Richter (it's inventor) of the California Institute of Technology .

• Formula:

The Richter scale defines the magnitude of an earthquake to be 

→ R=log(log($\tt l_c$$\tt l_n$))

 where $\tt l_c$= the intensity of the earthquake

and $\tt l_n$ is the intensity of a standard earthquake.

It can also be expressed as the difference of two magnitudes as

:⟶$\tt R_2$ −$\tt R_1$=log($\tt l_2$$\tt l_1$).
