What is the difference between candela, lumens, and lux, and how do they each measure the brightness or intensity of light?
Candela measures the intensity of light emitted in a specific direction, lumens measure the total amount of light emitted by a source, and lux measures the amount of light that falls on a surface. Candela is used for directional light sources like flashlights, lumens for overall brightness of a light source, and lux for the brightness of light on a surface.

What is the difference between lumens, candela, and lux, and how do they each measure the brightness or intensity of light?
Lumens measure the total amount of light emitted by a source, candela measures the intensity of light in a specific direction, and lux measures the amount of light that falls on a surface. Lumens indicate overall brightness, candela measures brightness in a specific direction, and lux measures brightness on a surface.
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 the difference between lux and candela and how do they affect the measurement of light intensity?
Lux and candela are both units of measurement for light intensity, but they measure different aspects of light. Lux measures the amount of light that falls on a surface, while candela measures the brightness of a light source in a specific direction. Lux is used to determine the brightness of an illuminated area, while candela is used to measure the intensity of a light source. In essence, lux measures the light that is received, while candela measures the light that is emitted.
Is luminous intensity vector or scalar?
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.
What does the metric symbol candela stand for?
Candela (symbol: cd) represents luminosity, the intensity of emitted light. It's not a metric symbol, but a photometric symbol.

What is difference between candela and kelvin?
Candela measures luminous intensity, or brightness perceived by the human eye, and is used to quantify the amount of light emitted by a source in a particular direction. Kelvin measures color temperature, indicating the hue of light emitted by a source, with lower values representing warmer (yellowish) light and higher values representing cooler (bluish) light.
Is luminous intensity vector or scalar?
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.
What unit measures light intensity?
in foot-candles. i.e. the brightness of a candle one foot away
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.
What does the metric symbol candela stand for?
Candela (symbol: cd) represents luminosity, the intensity of emitted light. It's not a metric symbol, but a photometric symbol.
What is te SI base unit for luinous intensity?
Intensity is measured in Candela. Candela is its SI unit.
What is the unit of luminious intensity?
candela--------------------------------------------The official international definition of candela (1979) is:"The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 x 10e12 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian".
Si unit for light intensity?
Light intensity is also known as luminosity. Candela is the si unit
What is the luminous intensity standard?
candela
