Why do scientists measure light intensity?
to know how is the light heavy
What equipment is used to measure light intensity?
a photodiode
How do you measure a candela?
it measures the intensity of light of a specified frequency
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
What does a spectrometer measure?
A spectrometer measures properties of light of a specific part of the wavelength. It is often used to measure the intensity of a light.
What is measure w?

What unit to measure intensity?
Intensity of what, exactly - light, magnetic flux, smell? You're going to have to be more specific.
Instrument used by umpire in cricket to measure light intensity?
lux meter or light meter
When light is reflected are the lumens reflected too?
Yes. The lumen is a measure of the strength of light; if light may be detected , it is done via the presence of photons, their intensity is the measure of luminosity.
What is the instrument for measuring light?
A photometer would measure the intensity of light, and a spectrometer would determine which frequencies are present.
What is a luminometer used for?
A luminometer, also known as a photometer, is used to to measure light intensity.
