A shadow is formed.
The phenomenon is called Rayleigh scattering. White light from the Sun is scattered going through the atmosphere. The Sun's rays coming pretty much straight down aren't scattered much, but rays going sideways through the atmosphere - the sunrise and sunset rays - are scattered. Red light is scattered least, so those sunset rays make it through to make the sky appear red, while blue rays are scattered more. The blue light rays are scattered toward the ground, and this makes the sky appear blue.
When light rays hit a rough surface, they are scattered in many directions due to the uneven surface of the object. This phenomenon is known as diffuse reflection, where light rays reflect off the surface in a random manner. This is why we are not able to see a clear image in a rough surface compared to a smooth surface.
Some light that falls on any surface is scattered back (reflected). A rough surface tends to scatter the light in different directions while a smooth surface tends to scatter more of the original (incident) rays straight back. This explains why a smooth surface reflects a "clearer" image than that reflected from a rough surface.
Light will be both absorbed and will be reflected unevenly (scattered) when impinging on a surface that is irregular. It depends on the light and the surface, but some light will be absorbed, and the rest (a little or a lot) will be scattered when it is reflected in different directions.
In dark field microscopy, the light that reaches the objective only comes from light rays that are scattered by the object being observed. These scattered rays are then captured by the objective lens, illuminating the object against a dark background. The dark field condenser blocks the direct light rays that would otherwise create a bright background, allowing only the scattered light to form the image.
Light rays are scattered when they encounter particles or objects that are much smaller than the wavelength of the light. This interaction causes the light to change direction and spread out, giving rise to phenomena such as diffusion or reflection. Scattering is responsible for the blue color of the sky and the white appearance of clouds.
You see the reflected light being scattered in different directions.
the reflection of light...I think
When parallel rays of light hit a rough or bumpy surface, they get scattered in different directions due to reflection. This phenomenon is known as diffuse reflection. The surface roughness causes the light to reflect unevenly, leading to the diffusion of light in various directions.
Regular reflection and diffused reflection both involve the bouncing of light off a surface. In regular reflection, light rays reflect off a smooth surface at the same angle they hit the surface. In diffused reflection, light rays reflect off a rough surface in many different directions, creating a scattered pattern of light.
The roughness of a surface affects reflection by scattering light in different directions. A rough surface will produce diffuse reflection, where light rays are scattered randomly, resulting in a dull appearance. In contrast, a smooth surface will produce specular reflection, where light rays are reflected at the same angle, resulting in a clear and mirror-like reflection.
Specular reflection occurs when parallel rays of light hit a smooth surface and reflect off in a uniform direction, such as with a mirror.
