to measture the length of objects
A meter is defined as the distance travelled by light in free space in 1/299,792,458th of a second.
it is use to measure electric potential (voltage).
To measure length, height, width of an object.
A one diopter prism will deviate a ray of light 1cm at a distance of one meter.
Function of the KWH meter is to record the electrical energy.
What's the function of meter rule
who envented light meter
Scientist use a light meter to show how light in shining on a surface !
If you mean a light meter that is used in a photographic studio, then it measures the light that hits the 'subject' from the studio lighting, the light meter then tells you what you need to set your camera to, for the correct exposure.
lux meter or light meter
800 meter is equl to how many kilometers
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.
100 quintillionths of a light year are in a meter http://en.wikipedia.org/wiki/Light-year
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.
One meter is about 0.000,000,000,000,000,105,7 light-years.Calculation: As a light-year is 9,460,730,472,580,800 meters, one meter equals 1/9,460,528,400,000,000 light-years = 1.057,000,834,024,615,4 × 10-16 light-years - or about 105.7 atto-light-years.
A meter stick is similar to a yard stick. HOWEVER, a meter stick measures 1 ( one ) meter, while a yard stick measures 1 ( one ) yard. I meter = 1.0936133 yards. ( round off to 1.1 yards approximately )
