What else can I help you with?
How can you see path of light through smoke?
You can see the path of light through smoke because the particles in the smoke scatter the light. When light enters the smoke, it hits the particles and scatters in different directions, making the path of the light visible. This effect is commonly seen in settings like laser light shows or sunbeams filtering through smoke-filled rooms.
Why can't we see a laser beam?
Laser beams are typically invisible to the human eye because they emit light in a very focused and narrow wavelength, often in the infrared spectrum. The lack of scattering and diffraction in laser light prevent it from being visible unless it interacts with particles or surfaces in its path.
Why can you see a light from a laser beam?
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.
Why can you see the beam of a laser if you spray water on it?
When you spray water on a laser beam, the water droplets act as tiny lenses that scatter and refract the light, making the beam visible. This effect is similar to seeing the beam in a foggy room, where suspended particles in the air create a visible path for the light to follow.
Why cant you see a laser beam as it crosses the room?
You can't see a laser beam crossing a room because the laser produces a narrow, focused beam of light that is not scattered easily. The light particles in the laser beam are not interacting with the air particles in the room, so there are no particles for the light to bounce off of and become visible to the human eye.
How can one see a laser beam?
To see a laser beam, you can use special materials like smoke or fog to make the beam visible. The light from the laser reflects off these particles, allowing you to see the beam.
Why can you see a path of light in a sunbeam?
You can see a path of light in a sunbeam when there are particles in the air, like dust or pollen, that scatter the sunlight. This scattering causes the light to become visible and creates the beam that you can see.
Why can't you point laser pointers at tv?
You cant see it because it has a light and the tv has a light.
What is a type of elctromatic wave that you can see and that transfers energy?
Laser light.
Why wouldn't we see a laser beam coming?
By definition, a laser travels at the speed of light. As soon as one sees it, it has already arrived via visual light.
How can we see a lazer beam?
If one shines into your eye (don't do this it is dangerous) then you would see it directly. However, a lazer beam going past you would be invisible UNLESS there was a substance in its path that could reflect parts of its light back to you (such as mist or dust).
What is the difference between a laser light and the light given off a filament lamp?
Laser light is said to be coherent; regular light such as the type produced by an incandescent bulb is incoherent. In coherent light, all the wavelengths are the same, and all the directions are the same, everything lines up and is perfectly uniform. With incoherent light, you get a messy mixture of wavelengths and directions. Light from a laser is collimated - i.e. aligned such that all the light rays are oriented parallel to each other. For this reason, you do not see laser light unless some of it is deflected by striking a something in its path or you are looking directly at it. In a filament lamp, the light rays are oriented in nearly all directions.
