Işık Hızı

Tanım

Işığın vakumda hareket ettiği tam hız: saniyede 299.792.458 metre; 1983'ten bu yana metrenin tanımında kullanılmaktadır.

Açıklama

Because the speed of light is fixed by definition, the meter is now defined as the distance light travels in 1/299,792,458 of a second. At this speed, light circles the Earth 7.5 times per second and travels from the Moon to Earth in about 1.28 seconds. Nothing with mass can reach this speed: at 99% of c, time dilation already causes a factor of 7 difference between moving and stationary clocks.
