Light intensity.
it is a unit rate
Unit rate
the physical quantity is distance and unit is meters
the formula showing the relation between the unit of any physical quantity n the unit of fundamental physical quantity is called dimensional formula.........of dat quantity
To measure a physical quantity correctly and need to compare it with some standard quantities. Thus a standard unit is needed to measure a quantity correctly.

lux
Lux is used in measuring luminous flux per unit area.
The lux is the SI unit of illuminance, and is equal to 1 lumen per square meter.
A lux (lx) is the SI unit of iluminance, or light intensity as seen by the human eye.
LUX is the measurement of illuminance and luminous emittance from light sources.
A quantity is a numerical value that represents the amount or measurement of something, while a unit is a standardized amount used to measure that quantity. Quantity is the actual numerical value, while unit is the specific measurement scale used to quantify the quantity.
A standard use for a measurement of a physical quantity is called the unit of that physical quantity
The unit of measurement for the quantity represented by the keyword "m unit" is meters (m).
The quantity in unit rates refers to the amount or number being measured or compared in relation to a single unit of another quantity. It helps to determine the rate at which the original quantity is changing or occurring.
