How fast does EM energy travel?
Speed of light.
Some fast do light rays travel?
Yes, they travel some fast!
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.
How fast does light travel through copper?
Copper is opaque to light - light can not travel though it.
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 do you Compare and contrast light and sound energy?
Light energy consists of electromagnetic waves that travel at the speed of light, while sound energy consists of mechanical waves that travel at a much slower speed. Light energy does not require a medium to travel through, whereas sound energy does. Light energy can travel through a vacuum, whereas sound energy cannot.
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)
Does light travel fast outer space?
yes
How fast does lighthouse beam travel?
at the speed of light
