How are infrared lasers used to measure speed?
Infrared lasers measure speed by sending out a light pulse, which is then measured by calculating the time it takes to hit the target and rebound back. It works in the same way an echo does.
What 3 things measure speed?
You can measure speed with items such as a Speed gun, Anemometer (wind), and a Speedometer (used in a car)
What is used to measure the speed of a moving body?
A commonly used device to measure the speed of a moving body is a speedometer. It measures the instantaneous speed of a vehicle by calculating the rotational speed of the wheels and converting it into a speed reading. Other methods such as radar guns or GPS devices can also be used to measure speed accurately.
What equation is used to measure wave speed?
speed= frequency x wavelength
What is the aneometer used to measure?
Wind Speed (knots)
Who is the scientist use the light year to measure the speed of light?
It doesn't work that way. The light-year is not used to measure the speed of light. It works the other way round: First, the speed of light is determined through other methods, then the distance called a light-year is calculated based on that measurements.
Are decibels used to measure light?
Absolutely. Photographic light meters are designed to measure light for photographic exposure (in a film-speed/shutter-speed/aperture combination), but many hand-held photo light meters can measure light in footcandles, which is a common scale. If you look on places like eBay, you can find inexpensive, digital, brand new meters which read out in Lux or Lumens. Some may read in footcandles as well. It's not difficult to convert from one measure to another (there should be internet calculators which would do it easily).
The instrument used to measure wind speed is a?
No. The instrument used to measure wind speed is an anemometer.
What is the SI measurement of light?
There is no "measurement of light". The units used depend on what you want to measure: its speed, frequency, wavelength, energy per photon, etc.

Is light years per century a unit of speed?
While it is truly an unconventional (and not very useful) unit, yes it is. Speed (and velocity) are shown as a ratio of elapsed distance to time. Therefore, since a light-year is a measure of distance and a century is a unit of time, this is a unit of speed (or it could be used to measure velocity).
What is a sensor used for?
A sensor is used to measure data from the environment and is able to convert them into signals to be communicated with a system. Most sensors are used to measure light, temperature, touch, sound, position and magnetism. Others are used to measure speed pressure, flow or are capable of recognizing images.

How many computer bytes per second equals the speed of light?
While the electric current which is used to communicate data in a computer propagates roughly with the speed of light, the question compares apples with pears and cannot be answered thus. The speed of light is a measure of speed, in a unit of distance over time. A data transfer rate, as might be expressed in bytes per second, is a measure for a quantity over time.
Is there yet a new thechnology that can send or transfer information at a speed of light in any place of the world?
"Radio" is a technology that carries information at the speed of light, wherever it is used, and is expected to become very popular as a result. Investment might be wise.
