How fast does EM energy travel?
Speed of light.
How fast does the sun's energy travel through space?
Most of the Sun's energy is radiated as light, and other electromagnetic waves. These travel at about 300,000 km/sec.; to be precise, the speed of light is exactly 299,792,458 meters per second.
Some fast do light rays travel?
Yes, they travel some fast!
Is there anything that can travel faster than the speed of light?
Nothing has been found that can.However there is a theoretical prediction of particles that can ONLY travel faster than light (at 0 energy they travel infinitely fast and it takes the addition of kinetic energy to slow them down), they are called "tachyons".
How fast does light travel through copper?
Copper is opaque to light - light can not travel though it.
How fast does light travel per foot?
the speed of light
How fast does light really travel?
it can travel from 380nm [nanometres] to 740nm
What does light energy travel in?
waves
What is darkness and how fast does it travel?
Darkness is the absence of light and will therefore travel at the speed of light (6x108m/s)
What travel fast light or sound in the universe?
light travels faster.
What is the difference between speed and light?
Speed is how fast something moves. Light is a form of energy carried by massless photons, these photons move at the speed of light, which is the fastest speed that anything in the universe can travel.
How does the energy of a gamma ray compare to the energy of light?
they're both fast, but not as fast as me in bed ;)
