All forms of electromagnetic energy have the same speed in vacuum . . .
299,792,458 meters (186,282 miles) per second.The speed is somewhat less in material media, and depends on the medium.
What else can I help you with?
How fast does EM energy travel?
Speed of light.
How fast does light energy travel?
299,792,458 meters/second
What is an antonym for radiant energy?
There is no such thing. You can define antonyms for simple properties, such as "tall", "fast", "dumb", etc., but for most objects, it doesn't make much sense to talk about antonyms.
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!
Why can an object with a nonzero mass never travel as fast as the speed of light?
An object with mass cannot travel at the speed of light because as it approaches the speed of light, its energy and momentum increase infinitely, requiring an infinite amount of energy to accelerate further. This is not possible due to the limitations of mass and energy in the universe.
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 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 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.
