The mechanical instruments like springs and levers are done by analogue scales whereas electronic scales use electronic load sensors and the digital signal is displayed on LCD or LED. Note: Non linear scales are those sales which have adjacent graduations that are not equivalent. Therefore the correct answer is option D. Thus, the human perception of sound intensity more closely estimates the logarithm of intensity, instead of assuming a linear relationship. An earthquake of magnitude 8 is not twice as destructive as an earthquake of magnitude 4. However this is not true and such an event does not happen. If the richter scale was a linear scale then the earthquake with magnitude 8 would have been twice as destructive as the earthquake of magnitude 4. One was of the magnitude 8 whereas one was of the magnitude 4. Let us take the example of two earthquakes. Richter scale is also not a linear scale. In such a case the decibel can be used to express the absolute level of the physical quantity. Decibels are measured using a logarithmic scale, which is different from the commonly-used linear scale. With more amplitude comes a louder sound. Electromagnetic Vibrations, Waves, and Radiation. where is the base-10 logarithm and is the threshold of hearing, The intensity is then described as being decibels, abbreviated dB. These physical quantities are often power or intensity and one of these physical quantities is taken as a reference value. Meanwhile, you use decibels to account for a sound’s amplitude, which is its forcefulness or pressure on the decibel scale. The decibel scale is a logarithmic scale that measures the intensity of sound. A simple example of this is a ruler.Ĭomplete answer:Decibel and Richter scales are not linear in nature.ĭecibel is a logarithmic scale and it is used to express the ratio between two values of a physical quantity.
Hint: A scale in which there is equal division for equal values then it is known as a linear.
