Relative intensity is measured in decibels and is abbreviated dB.
Relative density, is also called specific gravity, and it is the ratio of the density (mass/volume) of a substance to the density of a particular reference substance, usually water. So, where density has the units of mass/volume, relative density (specific gravity) is unitless.
comparative scale is a pair of scales having a common R.F. but graduated to read different units. A map drawn with a scale reading miles and furlongs can be measured off directly in kilometre and hectometre by a comparative scale.
The abbreviation of liters is "L." It is derived from the Latin word "litre." In the International System of Units (SI), liter is the unit of volume equal to one cubic decimeter, which is equivalent to 1,000 cubic centimeters.

Intensity
Intensity can be measured by converting units of electrical power in to decibels.
The intensity of vibrations is typically measured in units called decibels (dB) for sound vibrations, or in units such as meters per second squared (m/s^2) for mechanical vibrations.
Sound intensity I is measured in watts per meter squared (W/m²). Look at the link: "Conversion of sound units (levels)".
because thee is no proper intensity of incident radiation and there is cotinuously changing the intensity of incident radiation. ofcourse there is one colour at one time but at next time the light of next colour is allow to fall on the sample may by monochromator. (UOG students)
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.
Luminous intensity is a scalar quantity, as it only has magnitude (brightness) and no direction associated with it. It is typically measured in units of candela.
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.
Sound is measured in dB ( Decibels) for intensity and or Hz ( Hertz) for frequency or pitch.
Atomic radius is measured in picometres; 1 pm = 10e-12 m.
The psychoacoustic loudness N is measured in sones. The loudness level (Volume) LN is measured in phons. Scroll down to related links and look at "Conversion of sone to phon and the problem with dBA".
