A nice question to be thought about. Actually we cannot see the light passing in free space. While we look at the sunlight coming through a hole at home it becomes possible only when we have dust particles on its way. So in freespace as we don't have such particles we cannot see the light passing near by. Only when light falls on our retina we are able to sense it. Otherwise we cannot.
No, you cannot see a beam of light in space. In order for light to be visible, it needs to interact with matter and be scattered or absorbed. In the vacuum of space, there is no matter to scatter or absorb the light, so the beam itself would not be visible.
The Hubble Space Telescope can see out to a distance of several billions of light-years.
No, Antarctica is not the only place that has been seen from space by astronauts. It has been said that one can clearly see the Great Wall of China from space. Also there are certain places on earth that are clearly seen from space because of it's certain type of peculiarity. It is said that the beam of light from the Luxor Hotel & Casino in Las Vegas can be seen from space.
Most lasers can be seen, and yes a green laser beam can be seen in space. But some lasers are really strong so we can't see them.
because light is reflected off stars
Yes. See sunlight as a prime example.
You can only see a beam of light if there are particles around it. So say there was a man standing under a street light, and the world around him was foggy, you could then see the beam of light coming from the street light. And its the same principal with any luminous object. If there's no particle around, then you can't see the beam of light.
If you see the beam, you are seeing the scattered light being reflected off particles in the air. Any light you actually see is no longer laser light, assuming you have sense enough not to look at it directly.
scattering
Because of the refraction of the room and the light
you can see the beam a lazer by shining the lazer at a wall with the lights turned off then spraying something of a mist over the lazer beam.
Light waves travel in Straight Lines, but when a light beam passes close to a massive object, then the light beam will be deflected by the Gravity Well of that body. Otherwise known as the Curvature of Space-Time.
By definition, the word "visible" means something you can see. Beware: you cannot see a light ray or beam or photon as it whizzes past you. You only see those rays that enter your eye. In a dusty atmosphere you might say you can see a light beam, but what you see is that part which is scattered into your eyes.
You can see light rays with dust, flour, etc. If you turn on a flashlight, you can drop dust right where the light travels to actually see that beam of light. The same thing happens with red laser beams.
Water will bend a beam of light. Try this put a stright pincil in a glass of water. The pencil is still stright but looks bent. The water is bending the beam of light.
A detection beam on a microscope is a beam of high energy light. The beam allows individuals to see clearly and in more detail the substance or object under the microscope.
a type of light, from a beam of light
Project a beam of white [complete] light through a prism.
