What do you use to measure light?
there is an instrument called lux meter. i believe that it works with a complex electronics circuitry using light sensitive devices. it directly gives the reading in lux.
What will be the color reflected by a green surface when yellow light is incident on it?
No light will be reflected, since there is no incident green light to reflect. To a human observer, the surface will appear black.
How do I convert price per 100 meter to price per cubic meter?
You cannot. a meter is a measure of length, a cubic metre is a measure of volume. There is no conversion factor between the two.
How do you measure incident light?
Incident light is the light that falls from the source onto the subject. It is usually measured with a hand-held instrument (often digital, these days) called an incident-light meter. Readings are usually taken from the subject's position, with the receptor-cell of the meter facing back toward the camera. Some incident-light meters are dedicated to that function. Others can measure "reflected" light (light that is reflected from the subject) and have a module for measuring incident light as well.
What object could you use to measure the brightness of the bulb?
An item called a LUX meter is usually used for the determination of the brightness of a light bulb. It is generally a meter that measures the amount of incident white light.
What percent of incident light is absorbed in the first meter of seawater?
55%
Instrument used by umpire in cricket to measure light intensity?
lux meter or light meter
What metering system would you use for an indoor food shoot with only window light?
The best tool for the job would be an incident light meter, to measure the light that falls on the subject rather than the light that reflects from it. Most hand held incident meters are also reflective meters. Failing that, an 18% gray card and a meter reading of the entire card (does not have to be in focus; taking care not to cast a shadow on the card) would also be good.
How would you measure the brightness of light being produced by a source?
photometer or light meter
Who invented the light meter?
A light meter is used to measure the amount of ambient and reflected light in photography. This helps to determine the proper exposure for a photograph. A company called Weston marketed the first photographic light meter in 1932.
How do you measure light under room conditions?
Using a Direct or Incidence reading Light Meter.
Can you measure lighting?

What is an albedometer?
An albedometer is an instrument used to measure the albedo - the fraction of incident light or radiation reflected by a body - of a surface.
What does a UV Meter measure?
Ultra violet light - the strength of the uv rays coming from the sum
What is a unit of measuring wavelength of light?
The SI unit is meter. But nanometer and angstrom are commonly used units to measure the wavelength of light.
