299,792,458 meters (186,282 miles) per second, in vacuum; less than that in stuff.
The velocity of visible light waves is the same as the velocity of radio waves in a vacuum, both traveling at the speed of light (approximately 299,792 kilometers per second).
Light travels at a constant speed of approximately 299,792 kilometers per second in a vacuum. This speed is often referred to as the "speed of light." Velocity, on the other hand, is a vector quantity that includes both speed and direction, so the velocity of light would depend on the direction in which the light is traveling.
Ceres' mean orbital velocity is about 17.9 kilometers per second.
The velocity of visible light in a vacuum is approximately 299,792 kilometers per second, which is also equal to 186,282 miles per second. It varies slightly when passing through different mediums such as air, water, or glass due to changes in its wavelength and frequency.
The equatorial rotation velocity of dwarf planet Pluto is approximately 56 feet per second.
