A luxmeter is equipped with an electronic eye. This eye takes in light and converts it into an electric signal, passing it on to a computer which calculates the data sent from the luxmeter and converts it into lux.
1 lux is approximately the amount of light generated from a regular candle 1 meter away. A full moon on a clear night is 0.27-1.0 lux and direct sunlight can vary from 32000 to 120000 lux.

The intensity of light waves is a measure of what?
The intensity of light waves is a measure of the energy carried by the waves. It is proportional to the square of the amplitude of the waves. The intensity of light waves determines how bright the light appears to us.
What is the light intensity formula and how can it be used to measure the brightness of a light source?
The light intensity formula is I P/A, where I is the intensity of light, P is the power of the light source, and A is the area over which the light is spread. This formula can be used to measure the brightness of a light source by calculating the intensity of the light emitted per unit area. The higher the intensity value, the brighter the light source is perceived to be.
What equipment is used to measure light intensity?
A light meter is typically used to measure light intensity. It can measure the amount of light in the environment in lux or foot-candles. Light meters are commonly used in photography, cinematography, and environmental monitoring.
What equipment to use to measure wavelength?
A spectrophotometer or a spectrometer can be used to measure the wavelength of light. These instruments disperse light into its different wavelengths and can accurately determine the wavelength of a particular light source.
What would you use to measure light intensity?
A light meter is typically used to measure light intensity. These devices capture the amount of light in a particular area and provide a quantitative measurement in units such as lux or foot-candles.
What instrument measures luminous intensity or flux?
Luxmeter measures luminous intensity. The SI unit of luminous intensity is candela (cd).

How do you measure a candela?
it measures the intensity of light of a specified frequency
How do you measure light intensity and what tools or methods are commonly used for this purpose?
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.
How do you work spectrophotometer?
. A spectrophotometer is a photometer (a device for measuring light intensity) that can measure intensity as a function of the color, or more specifically, the wavelength of light
Instrument used by umpire in cricket to measure light intensity?
lux meter or light meter
