Why might a scientist use a light meter?
Scientist use a light meter to show how light in shining on a surface !
What is a measure of light called?
Light intensity is measured in LUX, which is defined as LUMENS/square meter. Lumens derives from the base unit CANDELA.
What kind of light describes how many watts of power fall cross one square meter of area?
That's not a special kind of light - you can do that with any light. The power per area (e.g., watts per square meter is a measure of INTENSITY.
At what light intensity do you expect there to be no net productivity?
100% light intensity ?
What is a light intensity knob?
The light intensity knob is found on light microscopes and allows you to change the intensity of the light on the sample. Different light intensities allow you to view different parts more clearly.
Instrument used by umpire in cricket to measure light intensity?
lux meter or light meter
What is measured in watts per square meter?
Light intensity or irradiance
What is a foot candle meter?
The type of light meter that measures the light intensity in pictures is a foot-candle meter. They help in setting the camera right and help in calculating the best lighting.

How is laser light different from incandescent light?
The intensity of light from most light sources is inversely proportional to the square of the distance from the source. So the intensity two meters from an incandescent lamp is one quarter of the intensity at one meter, and at three meters from the lamp the intensity is one ninth of the intensity at one meter. Laser light ideally has the same intensity at any distance.

What is the light intensity in the arctic?
The light intensity is poop!
What device is used for electromagnetic radiation?
Electromagnetic radiation is just light. You can measure light with a light meter, which tells you intensity, or a camera sensitive to different frequencies. You can also use a magnetometer (Gaussmeter) to measure the B field component or a voltmeter to measure the E field component.
Is a black light safe to use as a night light to sleep with?
Yes. Provided it is a low intensity UV light. Don't use tanning equipment...
Is light meter and barometer the most useful when measuring environmental changes?
There are many tools used in measuring meteorological changes. The most useful tool depends on which factors are measured. A light meter or photometer measures light intensity while a barometer measures atmospheric pressure.
What are some of the most common uses of a HID light?
The are many uses for a high-intensity discharge lamp light for those that use one. The main use for the high-intensity discharge lamp lights is to cover a large area that needs light.
