If I had a red laser light, will i be able to see this red beam in space?
I'm not sure you would be able to see the beam coming from the laser light, but you should be able to see it when it hits a solid object.Fiona Rozario said:If I had a red laser light, will i be able to see this red beam in space?
No, I'm saying the reason we see light is because the reflected parts reach our eyes, you would still see the laser, but not the beam like you would on Earth because their is nothing to direct the light to your eyes until it hits something. It may be possible that a camera that uses different methods of capturing images than our eyes do can see the beam, but the naked eye can't see it because the light doesn't reach us. Now the only thing I know that could allow the beam to be seen(however slightly) without an object scattering the light is gravity, but I'm still learning if that's true.Fiona Rozario said:Do you mean to say that light (poly or monochromatic) needs to be scattered by something so that it may be seen?
If the light doesn't reach your eyes, it won't reach the camera.CrackerMcGinger said:It may be possible that a camera that uses different methods of capturing images than our eyes do can see the beam, but the naked eye can't see it because the light doesn't reach us.
It all depends, as does the question in the OP, in the relative orientation of the person and the direction of propagation of the light. Light travels in a straight line unless there is some object to make it change trajectory, through reflection, scattering, bending because of refractive index (e.g., optical fiber), or something similar. If the light is not aimed at your eyes, you won't see it unless part of it gets deviated towards you.CrackerMcGinger said:Now the only thing I know that could allow the beam to be seen(however slightly) without an object scattering the light is gravity, but I'm still learning if that's true.

Yes, the human eye can see a monochromatic ray of light in space. Monochromatic light refers to light that is composed of a single wavelength, which is what makes it appear as a single color to the human eye. In space, there is no atmosphere to scatter the light, which means that monochromatic light can travel much further and still be visible to the human eye.
The color of a monochromatic ray of light in space would depend on its wavelength. Different wavelengths of light correspond to different colors, with shorter wavelengths appearing as blue or violet and longer wavelengths appearing as red or orange. So, the color of a monochromatic ray of light in space would depend on the specific wavelength of the light.
Yes, there are several natural sources of monochromatic light in space. For example, stars emit monochromatic light at specific wavelengths depending on their temperature. The gases in nebulae also emit monochromatic light at specific wavelengths, which is what gives them their distinct colors. Additionally, some planets and moons also reflect monochromatic light from the sun.
Monochromatic light is different from other types of light because it is composed of a single wavelength, which means it appears as a single color to the human eye. Other types of light, such as white light, are composed of a combination of different wavelengths, which is what gives them their ability to create a range of colors.
Yes, technology can be used to create monochromatic light in space. For example, lasers can emit monochromatic light at a specific wavelength, which can be used for various purposes in space exploration and research. However, it is important to note that any artificial source of monochromatic light in space would still need to be visible to the human eye to be seen.
