Visibility of laser light in mist of water particles

Click For Summary
SUMMARY

The visibility of laser light in a mist of water particles is due to the scattering of light. When a laser beam passes through mist or clouds, the water particles reflect and scatter the light, making the beam visible to the observer. In the absence of these particles, such as in clear air, the light travels without scattering, rendering the beam invisible. This phenomenon is a direct result of the interaction between light and small particles in the atmosphere.

PREREQUISITES

Hello, I'm quite intrigued as to why when a mist of water particles (clouds etc) is being shined by laser light, the laser beam is seen clearly, all throughout the mist, but if you take the mist off, the laser beam is no longer seen. What's the theory behind this?


Thanks a lot
From Steven

You can only see light when it hits your eyes, so unless there's something--like mist or dust--to reflect the light to your eyes, you won't see the beam.
