to know how is the light heavy
Light!
A candela is a unit of measurement for light sources and light emissions. Light beams projects different color at different wavelengths, and a candela is used to measure the intensity of the light.
The light intensity is poop!
decibels measure the intensity of sound.
You take a measuring microphone with a sound pressure level meter.
scientists use fajita scale to measure hurricane intensity
The intensity of light waves is a measure of the energy that is carried by the waves. Light waves are electromagnetic waves.
The SI unit for luminous intensity is candela (cd).
a photodiode
it measures the intensity of light of a specified frequency
. 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
A spectrometer measures properties of light of a specific part of the wavelength. It is often used to measure the intensity of a light.
No. The Fujita scale is used to rate the intensity of tornadoes. Hurricanes are rated on the Saffir-Simpson scale.
Intensity of what, exactly - light, magnetic flux, smell? You're going to have to be more specific.
It stands for standard Weight, the unit for light intensity.
lux meter or light meter
Photometers measure intensity of light or light-based properties of surfaces or solutions. This makes the applicable to many situations. For example, they can be used in absorption spectroscopy. This process is used by scientists to determine concentration of colored chemicals in a solution.
