Occasionally doppler radar has measure wind speeds inside a tornado but.
Instrument for measuring light intensity is called.
It can be defined as an instrument that measures visible light.
In photometry luminous intensity is a measure of the wavelength weighted power emitted by a light source in a particular direction per unit solid angle based on the luminosity function a standardized model of the sensitivity of the human eye the si unit of luminous intensity is the candela cd an si base unit.
A photometer is a light sensitive device and measure the power of light.
Newer digital light meters measure light intensity in lux while older analog light meters usually measure light intensity in an older unit called the foot candle defined as 1 lumen per square foot.
The fundamental unit of radiometry is called radiant flux.
Amount of sugar in a solution seismometer.
For measuring length saccharometer.
So one lux is one lumen per square meter this relating brightness to distance from the source.
A photometer is an instrument that measures the intensity of the incoming light and quantifies it into numerical data.
Location on earth s surface used in naval navigation spectrometer.
The answer depends on if you re looking for the intensity of white light as the eye sees it or the physical energy per unit time of electromagnetic radiation.
What matters the most in terms of measuring light intensity is the actual number of lumens falling on a particular surface.
Intensity of light as a function of wavelength speedometer.
If it s the latter then it s a radiometer.
However what matters most in terms of measuring light intensity is the number of lumens falling on a surface which is expressed as lux.
One candela per steradian is termed a lumen which is the measure of light intensity people are most familiar with.
Properties of light spectrophotometer.
Ratings are based primarily on damage assessment.
There is no particular instrument used for measuring tornado intensity.
After using the joly photometer to measure comparative light intensities you can measure light intensity using an analog or digital light meter.
A photometer is an instrument that measures light intensity.
Speed velocity of a vehicle spirometer.
Photometry deals with the measurement of visible light as perceived by human eyes.
If it s the former then it s a photometer.
Seismic waves for example earthquakes sextant.
