The intensity of an earthquake is measured using the moment magnitude scale, which takes into account the seismic moment released by an earthquake. This scale assigns a single number to quantify the size of an earthquake, with each whole number increase representing a tenfold increase in amplitude. The strongest earthquake on record had a magnitude of 9.5.

What is Distinguish between intensity and loudness?
Intensity refers to the amount of energy in a sound wave, measured in watts per square meter, while loudness is the perception of intensity by the human ear, measured in units called decibels. Intensity can be objectively measured, while loudness is a subjective perception that can vary from person to person.
How is intensity different from loudness?
Intensity refers to the amount of energy an sound wave carries, while loudness is the perception of that intensity by the human ear. Intensity is measured in watts per square meter, whereas loudness is measured in decibels. So, while intensity is a physical quantity, loudness is a subjective experience.
What unit to measure intensity?
Intensity is typically measured in units such as watts per square meter (W/m^2) for light or sound, or decibels (dB) for sound. For electromagnetic radiation, intensity can also be measured in terms of irradiance or radiant flux. The specific unit used depends on the type of intensity being measured.
What is the intensity light weight is measured in?
Intensity of light is measured in units called lux (lx). Lux is defined as the amount of light intensity or luminous flux per unit area. It helps quantify the level of brightness perceived by the human eye.
What does intensity of sound depend on?
The intensity of sound is dependent on the amplitude of the sound wave. The higher the amplitude, the greater the intensity of the sound. It is measured in decibels (dB) and corresponds to the loudness of the sound.
Relative intensity is measured in units abbreviated as?
Relative intensity is measured in decibels and is abbreviated dB.
What is measured on the ritchet scale?
The intensity of earthquakes is measured on the Richter Scale.
What is the symbol for luminous intensity and how is it measured in the field of optics?
The symbol for luminous intensity is Iv, and it is measured in candelas (cd) in the field of optics.
What is the abbr for electric intensity?
The abbreviation for electric intensity is " I " the intensity is measured in amps using an ammeter.
What is Distinguish between intensity and loudness?
Intensity refers to the amount of energy in a sound wave, measured in watts per square meter, while loudness is the perception of intensity by the human ear, measured in units called decibels. Intensity can be objectively measured, while loudness is a subjective perception that can vary from person to person.
What is intencity of light?
It is luminous intensity measured in candelas
What is the word for the intensity of sounds as measured in units?
decibels
The intensity of sound is usually measured in?
Sound intensity I is measured in watts per meter squared (W/m²). Look at the link: "Conversion of sound units (levels)".
How are earthquake magnitude and intensity measured?
Earthquake magnitude is measured using a number of differing scales including the Richter scale, the moment magnitude scale and the surface magnitude scale. Intensity is measured using he Modified Mercalli intensity scale.
How is intensity different from loudness?
Intensity refers to the amount of energy an sound wave carries, while loudness is the perception of that intensity by the human ear. Intensity is measured in watts per square meter, whereas loudness is measured in decibels. So, while intensity is a physical quantity, loudness is a subjective experience.
How does the human ear respond logarithm to intensity?
Intensity can be measured by converting units of electrical power in to decibels.
What is te SI base unit for luinous intensity?
Intensity is measured in Candela. Candela is its SI unit.
