Light intensity is measured in LUX, which is defined as LUMENS/square meter. Lumens derives from the base unit CANDELA.
The standard measure used to determine the brightness of a light bulb is called lumens.
To measure the frequency of light accurately and effectively, you can use a device called a spectrometer. A spectrometer splits light into its different wavelengths, allowing you to determine the frequency of the light. By analyzing the spectrum produced by the spectrometer, you can accurately measure the frequency of the light.
When the amount of light reflected increases, it is referred to as brightness or luminance. This is a measure of how intense the light appears to the human eye.
Light intensity is measured using a device called a light meter, which detects the amount of light in a given area. Common methods include using a digital light meter, a lux meter, or a spectrophotometer to measure light intensity in units such as lux or lumens.
This is known as visibility distance. It refers to how far an object or light source can be seen clearly by an observer.
They measure them in light-years.
The measure of a light's frequency is called wavelength.
because it resides in the electromagnetic spectrum which is the measure of light.

light year the DISTANCE light travels in a year so 'light year' is not a measure of time.
Astronomers commonly use the unit of measurement called a "light-year" to describe vast distances in space. One light-year is the distance that light travels in one year, approximately 5.88 trillion miles or 9.46 trillion kilometers.
usually the space is measured in light years
A "Light Year".Roughly 5,878,700,000,000 miles .
Candela (cd) is the unit of luminous intensity of a light source in a specific direction. It is also called candle.
When the amount of light reflected increases, it is referred to as brightness or luminance. This is a measure of how intense the light appears to the human eye.
It doesn't work that way. The light-year is not used to measure the speed of light. It works the other way round: First, the speed of light is determined through other methods, then the distance called a light-year is calculated based on that measurements.
