No limit ... even across the universe ... until it hits something that absorbs it.
Astronomers regularly capture images formed by light that has traveled for
about 14 billion years before it hits the film or CCDs in their telescopes and
stops.
In that amount of time, the light has traveled something like 82,296,200,000,000,000,000,000 miles.
(rounded to the nearest hundred quadrillion miles)
As far as light can travel
How far does light travel in one hour
As far as you like. For example it travels from the sun and gets through our atmosphere without much difficulty.
There are more things for the light waves to bounce off of in water, so light can not travel in a straight line or as far.
Light can travel about 5.88 trillion miles in one lightyear.
It can travel about 5.86 trillion miles in one year. This is a light year.
Infrared light can travel through a vacuum and is limited by the strength of the source and the sensitivity of the detector. In space, infrared light from distant stars and galaxies can travel vast distances, enabling astronomers to view objects billions of light years away. On Earth, atmospheric absorption limits how far infrared light can travel.
how far u can travel at the speed of light in a year
Light travels about 300 attometers in one yoctosecond.
88,179,380,597,754.15 miles
3,725,647.941 miles.
It depends how bright the source is.
