Express the speed of light travels in water in the form of negative exponents
Answers
Answer:
The speed of light is exactly 299,792,458 metres per second. This because the metre, since 1983, is defined relative to the second and the speed of light, in SI Units. Or c= 2.99792458×1082.99792458×108 m/s.
Some people get terribly confused about the metre (or meter) being defined in terms of the speed of light and see a massive conspiracy theory - but it is just simply a convenient thing to do, and is done for other physical constants, such as Planck’s constant, Avogadro's number etc. Rather than have to keep updating our textbooks with the latest refinement to the measured speed, the numerical value of the speed of light is defined, and future refinements to the measured physical speed of light only alter the physical size of the metre.
Similarly, the speed of light in imperial units and US units is based on an inch of exactly 2.54 cm, and is therefore exactly 186,282 miles, 698 yards, 2 feet, and 5 and 21/127 inches per second.
