The speed of light is constant ( 3.00 x 10^9 m/s ) and is represented by the letter c.
They don't designate the speed of light, but they do define the meter as1/299,792,458 of the distance that light travels in one second in vacuum.
"Speed of light" is the correct term. Velocity refers to the speed of an object in a specific direction, while speed is the rate at which an object moves regardless of direction. The speed of light is approximately 299,792 kilometers per second in a vacuum.
Correct.
Doppler wind lidar is a type of radar that continuously measures the wind. It uses laser light to detect the movement of atmospheric particles and calculate wind speed and direction.
speed of light I think well it sounds right:)

James Clerk-Maxwell did. He was shown to be correct when the speed was actually measured.
it measures wind speed!! -bri it measures wind speed!! -bri
curiosity... is the correct answer
It isn't clear what theories you are talking about.
A sensor in the transmission, measures the output shaft speed.
Yes. Radio is a form of electromagnetic wave, so it travels at the speed of light. Since sound requires a physical medium and it is (theoretically) impossible for matter to attain the speed of light, the speed of sound can never be equal to/above the speed of light, and this statement is correct.
The speed of light, or c, is a constant. The speed of light is exactly 299,792,458 meters per second IN A VACUUM. That's 670,616,629.2 miles per hour or 983,571,056 feet per second.
Velocity measures the speed of an object in a specific direction. Unlike speed, velocity is a vector quantity that takes into account both the object's speed and the direction it is moving.
An anemometer measures wind speed.
A aneomometer measures the wind speed.
