Its speed has been measured accurately, using lasers.
Light travels at 299,792.211 km per second in a vacuum.
All electromagnetic radiation or massless particles are capable of moving as fast as light.
Ultraviolet light travels at the speed of light, approximately 186,282 miles per second (299,792 kilometers per second) in a vacuum.
Light travels at a speed of about 186,282 miles per second (299,792 kilometers per second). That means light can travel around the Earth about 7.5 times in one second! It's the fastest thing in the universe that we know of.
Light travels at a speed of approximately 30 centimeters per picosecond in a vacuum.
light travels very fast! it travels in the form of waves.

Light. Nothing moves faster than light
Light travels at 299,792.211 km per second in a vacuum.
no from what i have learned light travels faster then sound
We use light years to tell us how fast light travels.
Light travels at the rate of about 300,000 km a second.
1 light-year is 9,460,700,000,000 kilometers.
1)Light travels in a straight direction.2)Light travels very fast with the speed of 300,000,000 meters per sec.3)Light travels in all directions.4)Light travels in vacuum(empty space).5)Light reflects.6)Light refracts.
lighting travels at the speed of light
That means how fast it travels. ==================== c
The speed of light is not dependent on how long time it travels.
