\nThe particles on the path of light beams coming from the Sun are visible to us because dust particles in the air scatter light into our eyes.
\n<\/section>\n
\n– In a perfectly clean atmosphere, a beam of light passing through it would be invisible from the side. We see light when it enters our eyes.
\n– When light encounters particles in the air, such as dust, smoke, or water droplets, it interacts with them.
\n– Scattering occurs when light waves are deflected in various directions by these particles.
\n– Some of the scattered light is directed towards our eyes, making the path of the light beam visible.
\n– This phenomenon is related to the Tyndall effect, which is the scattering of light by particles in a colloid or suspension.
\n<\/section>\n
\nReflection typically occurs from surfaces, refraction is the bending of light as it passes from one medium to another, and polarization is the restriction of the direction of oscillation of light waves. While dust particles can reflect and refract light, scattering is the primary mechanism by which the path of a light beam through a dusty or smoky medium becomes visible.
