The speed of light through anything is determined by the electrical properties
of that environment, specifically the electrostatic permittivity and the magnetic
permeability. The result of what those numbers happen to be in empty space
is 299,792,458 meters per second.
Is there some reason that you'd expect that speed to be difficult for light ? I know
it seems to be impossibly fast when you think about it or measure it. But snails and
ants feel the same way when they watch you walking around. It's all relative.
What else can I help you with?
What makes light travel?
It only travels in the speed of light
What is speed does light travel?
Light travels at a speed of 186,000 miles per second, in a vacuum.
What can travel at speed of light?
Any massless "thing" like a photon and MAYBE a neutrino. NOTHING with mass can travel at the speed of light. Photons travel at the speed of light. The entire electromagnetic spectrum travels at the speed of light.
What is the mass of the body which travels in the speed of light?
The only thing that travels at the speed of light, is light. Light is also said to have no mass, therefore the only way for something to travel at the speed of light is for it to have no mass.
What travels at light speed besides engines?
Particles that have no mass, such as photons, travel at the speed of light in a vacuum. These particles exhibit wave-particle duality and can behave both as waves and particles. Light, as a form of electromagnetic radiation, also travels at the speed of light.
Does light travel at half the speed of sound?
No. Light travels at about 875 thousand times the speed of sound.
How long fast does lighting travel?
lighting travels at the speed of light
Why does radiant heat travel so quikly?
Travels at the speed of light.
What light travels the fastest red or yellow?
they both travel at the same speed ? :>)
Do asteroids travel faster than light?
No, asteroids do not travel faster than light. Light travels at a speed of about 186,282 miles per second (299,792 kilometers per second) in a vacuum, which is the maximum speed at which anything can travel in our universe. Asteroids typically travel much slower than the speed of light.
How does light travel witch is faster light or sound?
Light is much faster then the speed of sound. Sound travels at a speed of about 768 Miles per hour, when light travels at a speed of 186,282 miles per SECOND.
Which color of light travels fastest through a telescope lens?
All colors of light travel at the same speed in a vacuum, including through a telescope lens. The speed of light is determined by the medium it travels through; in air or a lens, all colors of light travel at the same speed.
