In order to be seen, light must reach the eye. Since laser light is coherent, it travels only along its line of propogation, so there is no light to be viewed from the side of the beam. However, when a laser beam passes through fog, it is reflected off of tiny particulate droplets of water in the fog (or smoke particles in smoke), so is diffused in all directions and can be observed. In order to be seen passing through water, there must be suspended particles in the water from which the light can be reflected. The beam should not be visible as it passes through perfectly pure water.

Can lasers go through water?
Yes, lasers can pass through water, but their effectiveness and ability to penetrate depend on factors such as the laser's wavelength and the water's clarity. In general, visible light lasers have limited penetration in water due to absorption and scattering effects, while infrared lasers can penetrate deeper.

A very cold ice cube may appear to smoke, but actually what you are seeing is water vapor. The air around the ice cube is cooled by the cold ice cube, and when it cools, water vapor in the air condenses into fog.
Why lasers do not travel in water?
Being primarily scientific or industrial instruments, lasers are not typically manufacturedwater-tight; when placed in water, their electronics usually fail.However, the beam of light emitted by a laser travels quite well in water.

Does smoke make the sun appear red?
No, smoke does not make the sun appear red. The sun appears red during sunrise and sunset due to the scattering of light in the Earth's atmosphere.
Why smoke particles appear as spots of light?
Smoke particles can appear as spots of light when light shines on them because they scatter and reflect the light in various directions. This scattering can create the appearance of bright spots or points of light within the smoke.
