Question

The speed of light in a vacuum is approximately 299,792,458 meters per second. Convert this speed to kilometers per hour (km/h).

A) 107,925,284 km/h

B) 1,079,252.84 km/h

C) 299,792.458 km/h

D) 1,079,252,840 km/h

Definition Definition Rate at which light travels, measured in a vacuum. The speed of light is a universal physical constant used in many areas of physics, most commonly denoted by the letter c . The value of the speed of light c = 299,792,458 m/s, but for most of the calculations, the value of the speed of light is approximated as c = 3 x 10 8 m/s.
