What are the different light intensity formulas used to measure the brightness of a light source?
There are two main formulas used to measure light intensity: luminous flux and illuminance. Luminous flux measures the total amount of light emitted by a source, while illuminance measures the amount of light that falls on a surface.
How does candle power works?
Candlepower measures the intensity of light emitted by a source, typically a candle. It is a unit of luminous intensity, indicating how bright the light appears to the human eye. The higher the candlepower, the brighter the light.
What is the difference between candela and lux in terms of measuring light intensity?
Candela measures the brightness of a light source in a specific direction, while lux measures the amount of light that falls on a surface per unit area. Candela is a measure of luminous intensity, while lux is a measure of illuminance.
What is quantity measured in candela?
Candela measures luminous intensity, which is the amount of light emitted by a source in a particular direction. It is a unit of measure for how bright a light source appears to the human eye.
What is the unit used to measure luminous intensity in the SI system?
The SI unit of luminous intensity is the candela.
What instrument measures luminous intensity or flux?
Luxmeter measures luminous intensity. The SI unit of luminous intensity is candela (cd).

What is the difference between a lumen and a candela?
The candela measures luminous intensity, whereas the lumen measures luminous flux. In simple terms, you can think of luminous intensity as being similar to 'brightness', while luminous flux is similar to the rate at which light leaves its source.
How does candle power works?
Candlepower measures the intensity of light emitted by a source, typically a candle. It is a unit of luminous intensity, indicating how bright the light appears to the human eye. The higher the candlepower, the brighter the light.
What is the Si of luminous intensity?
The SI unit of Intensity of light is CANDELA.
The measure of intensity in LIGHT?
The SI unit for luminous intensity is candela (cd).
