In Real World Application #20, you learn about the origins of equations. I was thinking about this the other day… Where do these complicated equations come from and who takes the time to figure them out? It is done by mathematically experimenting. Application Exercise # 3 : In addition to being measured in a laboratory, it is actually possible to derive mathematically the speed of light (c): c = 2.99792458 x 10 8 m/s Execute the research necessary to find the derivation of the famous velocity. The speed ( or group velocity) of light in a vacuum (no air, no water, … nothing) is exactly 2.99792458 x 10 8 m/s. The speed of light is now DEFINED to be 299,792,458 meters per

Unformatted text preview: second. A meter is defined as the distance that light travels in vacuum in 1/299,792,458 second. The length of a meter has been defined many times by very careful experiments. It's a big deal when someone does an experiment that gives the speed of light with more precision than the last experiment. The most recent experiment where the meter was redefined again was on Oct. 20 th 1983. The definition states that the meter is the length of the path traveled by light in vacuum during a time interval of 1/299,792,458 of a second. (299,792,458 m/s or 2.99792458 x 10 8 m/s)...
